Celebrity Break-Ups

One rarely has any clue whether to believe tabloid cover stories about love triangles, especially as they pertain to Justin Timberlake and Jessica Biel.

But their notoriously on-and-off relationship is once again in the news, and supposedly on the rocks, as the singer cozies up to ex Cameron Diaz!

At least that's what Us Weekly alleges is going on as they film the romantic comedy Bad Teacher, leaving Biel out in the cold, bitter and betrayed.

Who knows if any of that's true, but it makes for good gossip!

Rumors that he and Cameron flirt openly on the Valencia, Calif., set coincide with the latest report of Justin Timberlake and Jessica Biel splitting up.

A source says his public flirting with Diaz is deliberate, too.

"He tortured Jess by taking this role, and they are reaching a breaking point," a pal of Biel said. "The truth is, I don't know if they can survive this."

So ... they're still on? Didn't be betray her? We're confused.

Shooting the film is just like "old times" for Timberlake and Diaz, who dated for years before he began romancing Biel. We're still pulling for Britney.

There's "lots of laughing, making fun of each other, kidding around off camera. She's sassy with him ... and slick, prancing around in tight clothes."

Those actresses in tight clothes ... there's a cover story.

It may not seem noteworthy, but Us says Biel and Timberlake have been having "huge arguments" and Jessica gotten more "territorial and upset."

In turn, Timberlake gets turned off and turns more toward Diaz. Worst of all, "when [Jessica] is not around, he'll make fun of her to his friends."

The nerve of that jerk.

Melissa and Tammy Etheridge have broken up after nearly nine years and tow children together, the couple's rep said in a statement Wednesday.

The long-term partners decided to part ways this year: "Melissa and Tammy Etheridge are saddened to announce that they are now separated."

The former couple added in a joint statement: "We ask for consideration and respect for our family as we go through this difficult period."

Melissa Etheridge and Tammy Lynn Michaels exchanged vows in Malibu in September 2003. She then went by the name of Tammy Etheridge.

Tammy gave birth to their children – son Miller and daughter Johnnie Rose – in 2006, after Etheridge was diagnosed with breast cancer.

The Grammy-winning singer is also mother to two older children, Bailey, 13, and Beckett, 11, with her previous partner Julie Cypher.

Mel Gibson and Oksana Grigorieva, the Russian singer he knocked up while his marriage to his wife of three decades, Robyn was unraveling, have broken up.

They split after a year of dating and one five-month old baby girl together. Both now have kids by two people and are married to neither. Way to go, guys!

"They just drifted apart," says a friend of the couple of the amicable split. "They’re both working hard on their careers and trying to raise a baby together."

"They're still friends and they'll both raise Lucia together."

Mel Gibson and Oksana Grigorieva: It was a good run.

Gibson is in Mexico filming How I Spent My Summer Vacation, while Oksana Grigorieva is working on music. Next week she will perform in her native Russia.

In April of last year, the actor's wife of 30 years filed for divorce. Later that month, he and Oksana made their first public appearance together as a couple.

Shortly after that, they announced she was expecting and the Octo-Mel jokes started flowing. But hey, he handled it better than his infamous DUI arrest.

During their three years together, breakup talk has dogged Jessica Biel and Justin Timberlake, who are once again the subject of such rumors today.

Is it real, and permanent this time? Who knows. We've heard it before and we'll hear it again. Well, actually we won't if it's legit. But you get the idea.

According to the UK's Mirror (we know, we know), Justin Timberlake and Jessica Biel are finally done for – and this time it looks like it's for good.

Says one insider: "Justin truly thought he’d found the one in Jessica and she felt the same. But the relationship just didn’t seem to go anywhere."

Three years later, they just realized this?

"They’ve both been working incredibly hard and will remain friendly – but there’s no more romance," the source adds. "It was mutual and they agreed it was best to part ways if things weren’t going to head towards marriage and kids."

"They are both incredibly busy."

So basically, it was a fittingly boring end to a painful, boring relationship. "They both knew things were going to end for ages – it was just a matter of when."

The source goes on to relay that Justin has "enjoyed hot snogging sessions" with another lady and Jessica Biel has "let her hair down" with some other fella.

No word if any of the above is true.

Did Paris Hilton and Doug Reinhardt split up for the second time? Or the third time, or whatever the heck it would be at this point? Very possibly!

Despite being the frequent source of engagement rumors, Doug was recently kicked to the curb by Paris, according to a source cited by E! News.

"Obviously she broke up with him," says the source. Obviously.

Still, Paris herself was asked about the possible split earlier in the week and responded "all is good." But is it, really? Depends on how you define "good."

Has Paris kicked Doug to the curb for good?

The maybe-split comes after weeks of Hilton and Reinhardt being apart. Paris spent Easter with her family in Palm Springs, while Reinhardt was in Aspen with his.

Over the weekend, Paris was living it up and looking single in Las Vegas where she partied at Wet Republic and Tao, while Doug was once again MIA. What gives?

Sources say that Doug, the brother of Casey Reinhardt, had thought about visiting Hilton in Sin City to talk things out. So does that mean it's over? It's unclear.

"He was in Aspen with his dad this weekend and was considering stopping by Vegas on the drive back, but changed his mind," says our source. "I'm pretty sure that's why he went to Aspen... to hide out and try to get over her."

The plot thickens. Just wait until both of them get back to L.A. today. Odds on the police being called to Paris' house by the end of April? Slightly worse than them getting called to the home of Lindsay Lohan, but still, pretty good odds.

They tied the knot in a secret wedding over the holidays in 2008, but it didn't last too long. Anna Torv and Mark Valley recently ended their marriage, reports claim.

The couple separated a few months ago.

Torv and Valley met on Fox's show Fringe, on which she plays FBI Special Agent Olivia Dunham, and he played agent John Scott when the series began (he has left).

The former Boston Legal cast member now stars as the lead on Fox's Human Target.

We wish them the best getting through this difficult, though hopefully amicable split.

We're sad to report that Anna Torv and Mark Valley have split.

Man, this is not the week to be in a relationship with a Gossip Girl co-star.

Yesterday, we reported how Jessica Szohr and Ed Westwick reportedly packed it in after her alleged flirting with one of his friends. Now more trouble in paradise.

A source says that Gossip Girl's Leighton Meester has broken up with her longtime boyfriend, Sebastian Stan, who plays a recurring character on the CW series.

Here's a photo of the attractive, possible former couple ...

Is it all over for Lebastian?

The starlet and aspiring pop star (one of her songs will be featured on next week's episode, as others have been in) "doesn’t know how to be in a relationship."

To top it all off, "she doesn’t really like them,” a source told OK!.

Well, that can never be a good sign for a guy trying to date her.

In other Leighton Meester news, it's her birthday today! Out of the way, Kristen Stewart! Okay, don't get out of the way, you're cool too. But make some room.

Gossip Girl co-stars and real-life couple Ed Westwick and Jessica Szohr are no longer together after he allegedly heard about her cheating with one of his friends.

Handsome heir Marco Minuto, the New York Post reports, is the other man. After one of his other friends blabbed, panicked Jessica then flew to London from L.A.

The goal was to beg him to take her back, but sources say Westwick is still deeply hurt by the betrayal and unmoved by her gesture. One source told the paper:

"Jessica recently celebrated her birthday in L.A. and was being openly affectionate and flirty with Marco. They ended up back at the same hotel later that night."

"Nobody knows what happened behind closed doors, but her behavior shocked a lot of their friends. Word quickly got back to Ed, who's been filming in Europe."

Weak. You do NOT f*%k with Chuck Bass!

WTF: Did Jessica Szohr really betray Ed Westwick?

The source continued that "Ed immediately ended their relationship on the phone, and Jessica, who adamantly denied anything happened with Marco, was so distraught over this that she flew to London last Friday with just the clothes on her back."

In vain, it looks like. At least for now.

"She's been begging Ed to take her back, but he is deeply hurt by the whole ordeal. He can't believe that she carried on this way with one of his friends."

Marco Minuto is in the same circle of friends as both of the Gossip Girl stars. Sounds like kind of a douche if he'd hook up with his good friend's girlfriend.

A rep for Jessica Szohr said that "She's been celebrating her birthday with Ed in London" and denied she'd cheated, saying, "The story has no merit."

Westwick's and Minuto's reps had no comment.

When they first got together, it seemed like an odd paring between a goofball and a beauty.

Five years later, we're shocked to announce that Jim Carrey and Jenny McCarthy have broken up.

"I'm so grateful for the years Jim and I shared together," McCarthy said in a statement. "I will continue to be in his daughter's life and will always keep Jim as a leading man in my heart."

Carrey's rep also confirmed that "Jim and Jenny... are grateful for the many blessings they have shared and wish each other the very best."

Tweeted the funny actor: Jenny and I have just ended our 5yr relationship. I'm grateful 4 the many blessings we've shared and I wish her the very best! S'okay!

Both stars had been married before and always laughed off talk of ever walking down the aisle together. We hope each eventually finds what he/she is looking for.

Celebrity romances come and go so often, it's hard to get really attached to Hollywood couples. But who are we kidding, we're suckers for certain ones, so when relationships crumble for our favorite stars, it makes the room a little dusty sometimes.

With a Sandra Bullock-Jesse James divorce likely looming and ready to join the ranks of the most painful celebrity break-ups, here's a look at 10 that hit us hard:

10. Taylor Swift and Taylor Lautner. Okay, they were barely a couple ... and may still be. But this split rocked us to the core ... we really wanted it to work.

9. Lindsay Lohan and Samantha Ronson. Is Lindsay going to die? Is she going to return to men? Will they ever stop feuding on Twitter? We cannot deal.

8. Denise Richards and Charlie Sheen. The split of these two stars? Not wholly unexpected, given that it's Charlie Sheen. But it was still scandalous and sad.

7. Reese Witherspoon and Ryan Phillippe. Two sweet kids, seven years of marriage, always seen smiling and laughing together. All a facade, apparently.

6. Tom Cruise and Nicole Kidman. Before Katie Holmes, Cryise was married to Nicole for 10 years and had adopted two children before splitting up in 2001.

Those were the good ol' days ...

5. Nick Lachey and Jessica Simpson. Before she was sexual napalm and starring on low-rate reality shows, she was younger, hotter, married sexual napalm starring in higher-rate relative shows and also producing hit pop songs. Ah, 2004...

4. Britney Spears and Justin Timberlake. Admit it, how hard were you rooting for them to get married? Admit it ... how hard are you still rooting for that?!

3. Jon and Kate Gosselin. When seemingly harmless reality TV couples go haywire and become far bigger stars based on the celebrity gossip they generate.

2. Sandra Bullock and Jesse James. We're also sticking a fork in this one because she can't possibly take him back... right? The Oscar-winner and the bad boy seemed to be a uniquely wonderful fit ... until along came Michelle "Bombshell" McGee.

1. Brad Pitt and Jennifer Aniston. The ultimate Hollywood fairy tale couple had it all. A-list TV and film success, reeediculous good looks and a happy home life. Hearts shattered around the world when Brad and America's sweetheart split.

When and if they split, Jesse and Sandra will be up there with Brad and Jen on our list of most memorable, painful celebrity break-ups. Which one were you saddest about?
