Talk about baby mama drama! More of The Insider's interview with Justin Bieber's alleged baby mama, Mariah Yeater, 20, has been released -- and the footage shows Yeater breaking down several times -- and even walking out!

Yeater is shown footage of Bieber denying that he is the father of her baby, and she starts to cry.

A few minutes later, when asked about whether she fears investigation for statutory rape (she was 19 when she allegedly slept with Bieber, while he was 16), she starts to cry again.

And when asked if anyone who was also backstage at the Los Angeles concert last year where she and the Biebs allegedly hooked up could substantiate her story, she starts to ... cry again. Then, Yeater walks out of the interview.

Bieber's camp says he will take the paternity test that Yeater asked for in court in two weeks, when he returns from Europe. See more of Yeater's breakdown after the jump.

Ahh, the battle of the blazer-clad blondes!

Last night we spotted Lauren Conrad leaving the Elder Scrolls V: Skyrim launch party in Los Angeles (you know, because she just LOVES to stay relevant video games), and earlier in the day we caught her former Hills co-star Kristin Cavallari smiling as she shopped at the Grove in Los Angeles. LC rocked black skinny pants and pumps with her off-white jacket while KC opted for grey suede Louboutin booties and a short dress that showed off her sexy legs.

We hate to pit these two frenemies against one another, but we HAVE to ask...

Jessica Simpson is pregnant with her first baby, but she's already ready for the next! She tells E! in a new interview:

"Pregnancy is meant for me. I could be pregnant forever. I love it. I love the connection I have with my body. ... I want a lot of kids. ... I can't wait to meet my baby. I can't wait to be a mommy. I grew up in such a great family. ... We all cried, because everybody knows, 'This is everything Jessica's ever wanted!' ... This is the biggest dream come true for me."

And, of course, Jess couldn't give an interview without bringing up ... flatulence. She said one thing she loves about being pregnant is being able to break wind. "I would normally blame gas on a dog," she said. "Now I take full credit."

But more importantly (though farts seem to rank as pretty important to Jess), does she know the sex of the baby yet? Find out after the jump!

Kelsey Grammer seems to be loving life with new wife Kayte Walsh. The twosome were all smiles while out on a dinner date at Mercato Di Vetro in West Hollywood.

The 56-year-old star recently gushed about his younger wife to Piers Morgan. When asked about being with Kayte, Kelsey said:

“It was like all the planets had danced together into a segregated charm on our behalf."

Before marrying Kayte, Grammer was married to Real Housewives of Beverly Hills star Camille Grammer for 13 years. She's now dating 35-year-old bankruptcy lawyer, Dimitri Charalambopoulos.

Ain't love grand!

Kris Jenner appeared on The Tonight Show With Jay Leno on Tuesday, where she told Leno she doesn't know if daughter Kim Kardashian and husband Kris Humphries will reconcile.

"I don't know," she said. "I really don't know ... she's trying to figure it out." Kim filed for divorce from Humphries on Oct. 31 after 72 days of marriage.

Then, Leno asked Jenner a pretty obvious question -- if Humphries will appear on the upcoming season of Kourtney & Kim Take New York.

Duh, Jay! The show premieres Nov. 27, and trailers are totally playing up the breakdown of Kim Kardashian and Kris Humphries' relationship!

So, that answer (a yes, clearly!) aside -- Kris Jenner (who produces the show), made another, more interesting claim. She told Jay that the family doesn't edit things out for their numerous E! shows!

"We decided a long time ago when we first started doing these shows that we were going to be really just raw, and not edit ourselves," she said. "And we don’t take things out."

Forget the bad economy, save your money for Louboutins!

Model Rosie Huntington-Whiteley has some advice for women everywhere.

At Christian Louboutin's book launch at Barney's in Beverly Hills, she told Fox that the designer's shoes make her feel "like a woman. ... very sexy ... every girl should be lucky enough to have them."

And what's the 24-year-old's advice for how the average woman can afford the $700 heels?

“If you can save up for a pair put away a dollar a week," she said. "It is really worth it!”

So ... it would only take about 14 years to buy a pair. We'll get right on it, Rosie!

Kris Humphries, 26, has remained relatively quiet since Kim Kardashian, 31, filed for divorce on October 31. But his father, William Humphries, defends his son in the latest issue of Life & Style.

Says William:

"There was never a discussion about it — it just came out of nowhere and blindsided Kris. How could someone do that? ... Kris was completely surprised. The news was already published before he found out. Kris is] hurting, but we’re here for him. ... It’s not a nice situation ... "

Kardashian's camp has said that Kris knew his wife would be filing for divorce, but William says his son found out via the internet.

Since the announcement, suspicions have swirled over the validity of the marriage, and whether Kim married Kris just for TV ratings. She has insisted she "married for love."

Brittny Gastineau was spotted leaving her birthday party at Sur in WeHo last night, and the starlet looked like she had a blast celebrating with her family and close friends. Britt rocked a super sexy black tunic and tights, and even though she forgot a bra, she looked a-m-a-z-i-n-g!

The birthday girl blew us a kiss on the way out, and speaking of lips, look who else showed up:
