Fans of How I Met Your Mother are accustomed to big laughs.

In a couple months, they'll soon be treated to big boobs, as well.

Indeed, Kim Kardashian (along with Kendra Wilkinson, Heidi Montag and Spencer Pratt) will guest star on a January episode of the sitcom.

Might an upcoming cameo turn Kim Kardashian into a sitcom star?

We'll let the busty reality TV star explain her experience shooting the appearance, courtesy of a recent blog entry:

Everyone on the set was extremely kind and so fun to work with! Bob Saget, who is the show's narrator, and cast member Jason Segel were there as well as my own mother, who everyone got to meet. Ha!

I played the role of...(wait for it)... myself!  In the scene I am on the cover of a weekly magazine and I come to life! So, I had to film it all on a green screen!

I can't wait to see the show! I really had a great time and hope this opens up other opportunities for me in the acting world.

Britney Spears' much-hyped new album, Circus, is set to drop December 2 and MTV's documentary on her, "For the Record," airs on November 30 at 10 p.m.

In an interview for the special, Britney compares her life to Groundhog Day, the movie starring Bill Murray, whose character repeats the same day perpetually:

“There’s no excitement, there’s no passion. I have really good days, and then I have bad days... Even when you go to jail you know there’s a time when you’re gonna get out. But in this situation, it’s never ending. It’s like Groundhog Day every day.”

Britney Spears continued to philosophize:

“I think it’s too in control. If I wasn’t under the restraints I’m under, I’d feel liberated. When I tell them the way I feel, it’s like they hear but they’re really not listening. I never wanted to be one of those prisoner people. I always wanted to feel free."

We have no idea what she's even talking about, to be honest, although we are reminded of The Office quotes in which the Dunder-Mifflin Scranton employees pretend life is better in jail than work... where they must do the same things every day.

Here's a new MTV promo for the "For the Record" documentary ...

Britney Spears: For the Record Promo

Jessica Simpson says her pregnant sister Ashlee Simpson, who is due to give birth any day now, is trying to everything to make that baby come out.

"Different foot massages and stuff," Jessica said on The Ellen DeGeneres Show (airing Wednesday). "She's jumping around trying everything right now."

Ashlee will likely induce labor, but Jess won't say if it's a boy or girl.

"I can't say because they haven't said," Jessica Simpson said. "I'll stick my foot in my mouth and get in trouble and I won't be a good aunt."

Jessica also told DeGeneres that she's in love with beau Tony Romo.

"He is a good guy, and he's really just helped me along in life and taught me a lot about being comfortable being myself - which is important," she said.

To be the Dallas Cowboys starting quarterback, the alleged singer continued speaking, "there's a requirement. Like, you have to be good looking. Being out there and demanding and commanding that field - that's pretty sexy."

Losing the playoffs? Not so much.

Carol Alt is about to prove that you needn't be under legal drinking age to look good naked (yes, we're looking at you, Karissa and Kristina Shannon).

The long-time super model - who rose to prominence way back in 1982 when she graced the cover of the Sports Illustrated Swimsuit Edition - will pose naked for next month's Playboy.

Coming soon to Playboy: Carol Alt nude and Carmen Electra nude. Which are you more excited about?

Why is Alt, who has never posed nude before, choosing to put her elderly bare body on the line? She actually cites a change in diet.

“What was interesting to me at this moment in my life is not just my age... but I am a raw foodist and the only reason I look the way I do right now is because I changed my diet and started eating healthy, living foods, which are unprepared and unprocessed foods, the closest they can go from God to me”, she said. “That’s what I eat and my body shows it.”

The Playboy photo spread will be titled “Carol Alt In The Raw – The Body That Raw Built.”

Angelina Jolie is seen here in the backseat of a car, trying to remain stoic in the face of celebrity gossip photographers snapping her every move.

OR IS SHE?

Might this actually be a wax representation of the actress, as those monstrous lips don't appear to be moving?

You decide in another edition of Real or Wax ...

Angelina Jolie: Real or Wax?

Mindy McCready admits that she has "lived life recklessly" and made a lot of mistakes, like having an affair with Roger Clemens while she was a teenager.

Back in New York after a trip to Southern California to talk about possible reality TV projects (yes, really), the troubled country singer spilled her side (sometimes multiple sides) of her Roger Clemens affair to various media sources.

McCready told Inside Edition that her alleged affair with the beleaguered baseball star ended because she wanted him to leave wife Debbie Clemens. But she also told the New York Daily News that she "never wanted to marry" the Rocket.

"[Roger Clemens] should have done right by his family - if a person is unhappy in their marriage and spending all their personal time with someone else, you need to do right by your marriage," McCready told the Daily News.

"He should have just told Debbie and been honest with her. If he didn't want to be with her and wanted to be with me, he should have told her."

Meanwhile, according to Inside Edition, McCready stated that "I wanted him to, after all that time, do the right thing by me. And, Roger is loyal and dedicated to his family... and so I ended it." Multiple personality disorder, anyone?

Roger Clemens denies that anything sexual happened with Mindy McCready at any time and, in responding to her various claims, only issued a statement acknowledging that he has "made mistakes in my personal life for which I am sorry."

McCready is consistent in her sorrow for the pain she caused Debbie Clemens.

"I have nothing but remorse and nothing but sympathy for what she's had to go through with this situation and she has my utmost apology," she told Inside Edition. "I would apologize to her and say I was young. I now know better."

Last week's Adrienne Bailon nude picture scandal has come back to bite the singer in her (bare, exposed) ass.

A source told Perez Hilton that Bailon and the rest of the Cheetah Girls have been axed from the Macy's Thanksgiving Day Parade. It's not difficult to guess why.

"The Girls were scheduled to be in the parade and perform, but after Adrienne's recent photo incident, organizers didn't think it would be appropriate to have her at a family-oriented event," an insider said.

Does Adrienne Bailon's punishment fit her naked crime?

I’m going to salute you. You came out tonight and danced two fabulous dances.

- Len Goodman to Lance Bass and Lacey Scwhimmer

Such praise sums up last night's season seven semi-final on Dancing with the Stars. One couple distinguished itself from the others, as Bass and Schwimmer are all but assured of a spot in next week's finale.

Here's a rundown of all four tandems, their dances and their combined scores on the night:

• Brooke Burke & Derek Hough: 21 out of 30 for their jive; 28 out of 30 for their salsa. Total: 49 out of 60
• Cody Linley & Julianne Hough: 22 out of 30 paso doble; 24 out of 30 for their salsa. Total: 46 out of 60
• Warren Sapp & Kym Johnson: 24 out of 30 for their mambo; 25 out of 30 for their jitterbug. Total: 49 out of 60
• Lance Bass & Lacey Schwimmer: 28 out of 30 for their mambo; 29 out of 30 for their jitterbug. Total: 57 out of 60

Lacey Schwimmer and Lance Bass remain favorites to take home this season's Dancing with the Stars trophy.

Fresh off a Hawaiian vacation and a "business" trip to South Beach (where he happened to run into step-sis Kim Kardashian), Brody Jenner is talking all about it on his new, official blog. Yes, so you can keep track of all things Brody Jenner at all times.

In addition to updating you on his whereabouts, Brody can't help but gush about his new girlfriend, Jayde Nicole, who he calls "beautiful inside and out."

Hey, you really can't blame the guy, cheesy as he's being lately. If you were lucky enough to see Jayde Nicole naked, there would be many a post written.

Here are some shots of Jayde and Brody from his site ...

The earth-shaking comeback of Britney Spears rolls on.

Our girl's got a hit single, an album ready to drop in two weeks, a brand new website, a hot airbrushed body, a tour in the works and lots, lots more.

Today's announcement: Britney will be taking part in one the biggest annual holiday traditions: the lighting of the Rockefeller Center Christmas tree!

On December 3, the day after she turns 27 and her new album, Circus, hits record stores, Britney will be in the Big Apple for the tree-lighting extravaganza.

BACK ON TOP: Britney Spears' mega-comeback included some big wins at the MTV VMAs. Which are totally rigged and arbitrary, but that's neither here nor there.

What's still unclear is whether or not she'll be performing at the ceremony, or just hangin' around with host Al Roker for the NBC broadcast of the event.

We'd bet against her singing, since she sort of can't, whatsoever, in a live setting, but it's awesome that she's gonna be there in the heart of N.Y. City.

Speaking of Rockefeller Plaza, 30 Rock quotes are pretty funny. You should watch the show. It's actually pretty great even though it doesn't get much press.
