Chelsea Handler’s new sitcom, Are You There, Chelsea? debuts tonight on NBC, and while it’s been getting mixed reviews, lots of people are expecting it to be pretty good. Why? Because Handler has garnered herself a whole gaggle of fans from her stand-up comedy and E! show, Chelsea Lately. Turns out audiences respond really well to talking about your vagina and calling Angelina Jolie a c*nt.

On the show, Lara Prepon plays Handler, who is a standup comedienne on the show, too. Like a tall, blonde, female Seinfeld. To help kick off Chelsea’s show, we’re rounding up six other comediennes turned sitcom stars.

Following his 2005 divorce from Jennifer Aniston, Brad Pitt decided to buy a house in the ‘Bu. If you’re not in the know, the ‘bu refers to Malibu. Okay, no one actually calls it that.

Brad put his Malibu oceanfront home up for sale four months ago, and the actor suddenly withdrew the house from the market. He was asking for $13.75 million.

This place is seriously lavish, but compared to the castle he lives in with Angelina Jolie, it might as well be a cardboard box on Skid Row.

Alright, maybe not. At 3,300 square feet, the estate was originally built in 1962 and sits on top of a bluff off the Pacific Ocean.

These two got the fever. Baby fever, that is.

Russell Brand is truly a reformed bad boy, because he recently revealed that he's ready to be a family man.

When TV host Ellen DeGeneres asked whether he and his pop star wife are planning a family, Russell replied: "I would like one. I love those little babies in the beginning. They’re so lovely in that bit. Me and Katy are godparents to two twin boys. They’re called Sam and Donovan."

And Katy wonders why we all think her In-N-Out bump is a baby bump.

Russell jokes that at first, he wasn't that impressed with Sam or Donovan:

You gotta love Rihanna for not being afraid to put her desperation out there. While the singer was recently rumored to be dating a Chris Brown look-alike, she confirms that her relationship status is indeed single.

The You Da One singer went on the Ellen DeGeneres show and told the host, "I'm not dating anyone right now."

In fact, "I'm not dating at all," Rihanna added.

Well, that explains why she's been in heat the entire year.

"I'm not necessarily happy being single," she admitted. "It's not really that cool."

She added that she really doesn't have time to date, because she's so busy touring, showing off her butt...
