Jennifer Aniston and Gerard Butler took a break from promoting The Bounty Hunter and attended a party in Madrid last night, and not only did they cozy up inside, but Jen got onstage and shook her monkeymaker with several flamenco dancers. I know Jen is totally the girl next door, but surely someone noticed her sexy dance moves and made a pass last night! Maybe Gerard?

After the news broke that Jesse James cheated on his wife Sandra Bullock with no less than four different women, the reality TV star/mechanic has checked himself into a rehab facility.

His rep released the following statement: "Jesse checked himself into a treatment facility to deal with personal issues. He realized that this time was crucial to help himself, help his family and help save his marriage."

A source told X17online he checked in on March 26 at Sierra Tucson in Tuscon, Arizona, a clinic which specializes in all kinds of therapy, including help for sexual addiction. But is this too little too late?

X17 called the rehab center yesterday and a panicked receptionist declined to answer when we asked about Jesse James being a patient. She really clammed up when we asked if security had been tighted since his arrival ...

Oscar-winner Reese Witherspoon hides behind her hat and her hand after a day of shopping in Brentwood. Why so shy, Reese? You have a hot new hunk in your life soon after your breakup with Jakey G... nothing to be ashamed about!

And are those Lindsay Lohan's "Mr. President" leggings on Paris? I think so!

Princess P had a smile on her face after penciling in a little retail therapy at Fred Segal in Bev Hills on Tuesday with a gal pal, who made sure to snap pix of the paps on their way out. Either P just spotted a new outfit she likes OR it's boyfriend Doug keeping her in a good mood 24/7!

Sidebar, is Paris wearing flats? How Posh of her!

Work it, girl! The Hills might be coming to an end, but Kristin Cavallari's reign certainly has not...

The Laguna Beach native (who forgot to wear a bra) strutted her stuff in the BH yesterday in a tight tank and black leggings. Kristin should totally ditch reality TV and star in direct-to-DVD horror flicks. I'd rent 'em!

Spotted: TV hunk Josh Duhamel carrying a pretty-in-pink baby outside his Beverly Hills home on Tuesday. Joshie would make a great daddy!

But does this mean his wife Fergie could be preggers and this is Josh's way of getting ready? Probably not, but one can hope!

Kim Kardashian is moving on with her life after breaking up with on-again, off-again boyfriend Reggie Bush. And part of moving on is moving out.

Life & Style reports that Kim packed up all her things and moved them out of Reggie's house, where Kim had been living for the past eight months, before heading to Miami to shoot some episodes of Kourtney & Khloe Take Miami and spending time with her girlfriends.

A spy tells that mag that at the launch of Kelly Rowland's charity, I Heart My Girlfriends last weekend, Kim was overheard telling pal Serena Williams that she was "surviving after the breakup" by staying busy with friends and family. And that's exactly what she did later that night. "She really needed a wild night out with her girlfriends," says a source.

But when Kim returns from Miami, she'll be moving into the Beverly Hills mansion she's been busy remodeling.

The five bedroom home, which was purchased by Kim alone, was a big step up from the West Hollywood condo she lived in before, and we're sure that moving into her own dream home will help put even more distance between her and Reggie.

But even after all the allegations of cheating (which a source says she doesn't believe), Kim and Reggie are taking a pragmatic approach to the breakup.

"Kim's not heartbroken," another source tells the mag. "Her attitude's healthy. They split for a while, then they tried their best to make it work again. It didn't work." The insider adds, "They remain friends."

Well she IS sexual napalm, so of course we're going to make this comparison!

Last night Jessica Simpson and her father Joe had a dinner date at Boa in West Hollywood, and the daddy/daughter duo weren't exactly able to sneak out of the restaurant unnoticed. Then again, when Jess has her girls on display in a dress like this, she's gotta know how much chaos she'll cause...
