Girl-on-Girl Action

Teen Mom 2’s Kailyn Lowry has been in same-sex relationships - before and after giving birth to her now-2-year-old son, Isaac - according to Star and Radar.

"Kail" was with a girl named Shelby for about two years, ab insider tells the tabloid, adding the relationship started when the two were in ... middle school.

The insider said that Kailyn and the girl broke up when she started seeing Jo Rivera, who of course impregnated her with Isaac and feuds with her constantly.

“Jo knew about Kail’s relationship with that girl,” the insider said. “He thought it was a phase.” Maybe it was ... but maybe it wasn't, the source added.

Kailyn Lowry would soon find herself in another full-on lesbian relationship, cheating on Jo Rivera with female high school classmate Gigi Hanna!

“Kail cheated on Jo with Gigi, but he knew and didn’t care,” the source said.

Gigi told Star that she and Kailyn had an on-again, off-again romance that re-sparked after the young mom’s son, Isaac was born a few years ago.

“We became close and promised to never leave each other; we moved in together,” Gigi said, adding they shied away from PDA. “We know our boundaries."

The insider claims that both were involved with men at the time: “They were both seeing guys, [but] would make out and Gigi would sleep in her bed."

"Kail thinks they’ll both end up with a guy, but they’ll always be best friends.”

That's good to hear. You've been warned, new boyfriend Jordan.

J. Crew president Jenna Lyons' divorce from Vincent Mazeau has been playing out in the tabloids, with conflicting reports about just what transpired between them.

Specifically, when Jenna began dating Courtney Crangi.

"They met at a fashion event several years ago ... at least three years ago ... and became friends," a source close to them told People. "They got together this summer after Jenna Lyons' [nine-year] relationship [with Mazeau] ended."

The source also emphasized that the Lyons-Crangi relationship "absolutely" did not break up the Lyons' marriage. A Mazeau source, however, says otherwise.

The insider close to the fashion icon says Jenna Lyons and Vincent Mazeau still live together in their Brooklyn brownstone for the sake of their son, Beckett.

"They separated two years ago, and Jenna went through several months of trying to work it out. But two years later their problems got worse and worse."

A source close to Mazeau takes issue with that perspective, however.

"Like most marriages, they had their share of ups and downs over the years, but despite what's been reported in the press, they were not split before Jenna and Courtney began their relationship," the Mazeau source says emphatically.

J. Crew president and creative director Jenna Lyons has been making news as of late because of her messy divorce from husband Vincent Mazeau, who's seeking a HUGE settlement, with whom she shares a son, and who she allegedly left for a woman.

Courtney Crangi has been identified as that woman.

Here's Jenna Lyons (left) and her new girlfriend ...

The fashionable pair heretofore known as Jourtney. On THG at least.

Courtney Crangi also works in the fashion industry, the NY Post reports, presiding over the business side of her brother Phillip Crangi's high-end jewelry line.

An insider tells Page Six that it was over between Lyons and Vincent Mazeau before their involvement: "After the breakup, Jenna fell in love with Courtney."

"The two had been close friends for some time."

"She and Courntey known each other for years through the fashion business. Courtney is an attractive blonde who balances working hard with her family."

Reportedly Jenna and Courtney have been seen out and about together in NY City's West Village and are quietly open about their new relationship.

Is Deena Nicole Cortese actually bisexual, or just putting on a show for MTV cameras? Unclear. Did she just pull a robbery on Sitch and Vinny? Quite clear!

That was not a Jersey Shore plot line we saw coming. The exposing of Sitch and Snook's smush session and the Ron-Sam reconciliation, however, felt inevitable.

As always, we've recapped all the top Jersey Shore quotes and moments for you below. Let's break last night's episode, "Twinning," THG +/- style!

Snooki wants to grab a glass of wine with Ron before GTL. Lush. Minus 4.

He plans to have "the conversation" with Sam soon, he says. We're already feeling a bit scared, emotionally drained, and excited for the fireworks. Plus 5.

Snook feels Luigi's "weiner" at the gym. He nods and laughs, since he doesn't understand. Or maybe he does, which would be even funnier. Plus 3.

Deena is gettin' some Lean Cuisine. NOTE: Not the frozen dinner. Minus 2.

Britney Spears joined Rihanna at the 2011 Billboard Music Awards for some "S&M" last night. Their sexy duet ended in a kiss ... which ABC moronically cut off.

It didn't last as long as Britney's tonguing of Madonna at the 2003 VMAs, but the kiss was still captured by some astute (and possibly excited) photographers!

Apparently ABC wasn't a fan and quickly cut away from Britney Spears and Rihanna's performance in favor of a boring shot of the audience. So pics will have to do.

Not perfect, but when you've got Britney Spears and Rihanna quasi-making out in kinky S&M gear, how can you really complain? Exactly. So just enjoy ...

Contain yourselves, guys, even if it's hard.

You're in luck, fellas. Lindsay Lohan hasn't abandoned you yet.

Despite her long-term relationship with Samantha Ronson, Lindsay told Australian radio show she would absolutely consider dating a guy again.

LiLo went on The Kyle and Jackie O Show and was asked: "We'd love to know whether you're a lesbian or whether you're bi ... 'cause boys wanna know if they still have a chance ... have we still got a chance?" Her reply: "Yes."

Although she dodged additional questions about bisexual, when asked if she was dating anyone, guys in particular, she said: "I'm available."

Lohan also opened up about a range of other topics in her life - dating, community service, and that infamous white dress she wore to court.

She says she's clean for life, which no one out there is buying, but we do hope for the best, of course. So how is community service going?

"I'm enjoying it. I'm working in the Downtown Women's Shelter, and I think the second part I'm going to be working with kids, which I like."

As for her too-sexy-for-court fashion ...

Angelina Jolie is a sexual being. No one can deny this.

Still, we imagine the denials will come fast and furious with the star's camp gets wind of the new cover story in Invent Brangelina Gossip Touch Weekly.

Angelina Jolie has been running around on Brad Pitt, according to this unreliable, but hilarious tabloid report. The new twist to this age-old rumor?

She has mistresses. As in multiple, female partners.

Ever since she was a teen, Jolie has been known as one of Hollywood’s wildest, most profoundly sexual women - and not even Brad can quench that carnal thirst.

According to a "friend," Angelina harbors strong bisexual desires and continues to engage in flings with women behind Brad’s back. She even has a girlfriend!

And got rejected by a stewardess! We call BS on that part. Who's gonna turn down hot, heavy, girl-on-girl, Mile High Club action with Angelina Jolie?!

No flight attendants we know, that's for sure.

Kendra Wilkinson can't seem to escape her wild past.

The latest development in the former Playboy centerfold's saga is the discovery of yet another Kendra sex tape, this time starring another girl!

Reports say the new tape shows Wilkinson, her ex-boyfriend Justin Frye and Kendra's friend, Taryn Ryan, going to town for close to an hour.

Sources who have seen the tape say it's reminiscent of Paris Hilton.

"Kendra and Taryn started fooling around and then Kendra wanted the light turned off," a source said. "But the camera recording it had night vision."

"It looks like the Paris Hilton porn tape. Everything is completely clear."

That's ... awesome? Probably depends if the first Kendra sex tape was your cup of tea. Like that one, this leaves "nothing left to the imagination."

Remind me to delete this video after we're done...

Following the successful release of Kendra Exposed last spring, sources confirm to Radar Online that another amateur porn starring this former Girl Next Door is out there, and it co-stars a female named Taryn Ryan.

"They were friends and were hanging out together, with their boyfriends," an insider says of Kendra and Taryn. "It's a long tape, about 45 minutes. And there is nothing left to the imagination."

Sounds hot!!!
