After a dinner date at Katsuya, Tila Tequila was spotted leaving Dave Navarro's Hollywood pad late last night. We're not sure if this was a raunchy booty call or if they were just snuggling and watching HGTV, but clearly Tila was dressed to impress!

And as for Dave, it seems like that last classy girl he dated was Carmen Electra -- since when did he resort to dating trashy and delusional reality stars trying to make it as porn stars? Eeks!

Natalie Portman graces the cover of Vogue's January 2011 issue, and the actress looks nearly as graceful as the ballerina she plays in Black Swan.

Of course, Natalie appears to have gained back most of the 20 pounds she lost for the film, but she still looks pretty trim in this shot. Natalie recently revealed that she worked out six days a week, eight hours a day to master her dance moves and shed the pounds, and if you've seen the film, you'll know it paid off!

Halle Berry took advantage of this weekend's gorgeous weather by taking adorable daughter Nahla to the beach in Malibu.

The two spent hours playing in the sand, splashing in the water and searching for that perfect seashell!

Great to see Halle juggling her busy movie career, a new relationship and remaining an awesome mom to her young daughter. We'll admit, these two are the cutest!

On Saturday Olivia Wilde attended the premiere of TRON in Hollywood, and even though we love the boys in the movie, girlfriend totally stole the show. This slinky gold number is even hotter than the $60,00 suit Ms. Wilde wore in the film, and that's saying something!

P.S. We must confess we caught an early 3D screening of the film, and it's mind blowingly awesome. The action sequences will have you on the edge of your seat, so be sure to check it out when it hits theaters this Friday! And if you want your Garrett Hedlund fix, here ya go:

Even though Nicole Richie's weekend nuptials to Joel Madden are being hailed as the celebrity wedding of the year (we're guessing it was because of the elephant), it sounds like there were a few headaches when it came to preparations last week!

The wedding was supposed to be on December 5, but a source tells X17online exclusively that as soon as Nicole learned the media was in on her big date, she "had a panic attack" and pushed it back to the next weekend. Nicole was also a bit frantic because her wedding dress wasn't finished, so she opted for the 11th, which is apparently her lucky number.

A source at the wedding tells X17online exclusively that brother-in-law Benji Madden made a very sweet toast, thanking Nicole for a beautiful niece and nephew and stating how thrilled he was to finally have Nicole as a sister in law. Aww! Benji also thanked Nicole for "completing Joel", and when Joel and Nicole exchanged their personal vows, father Lionel was very teary eyed and emotional.

Harlow' birthday is on January 11th, so we're glad Nicole was able to work it all out and give herself another lucky date on her annual calendar. Now if only she could sell those wedding photos...

While wife Angelina Jolie continues promoting The Tourist in Berlin, Brad Pitt and the kids took a moment to glance out the window of their historic hotel. Look how tiny Pax looks!

It's no wonder the family chose the Adlon Hotel for their stay while in Germany. At one time, the Adlon was one of the most famous hotels in Europe between the two World Wars ... hosting celebrities like Charlie Chaplin, Josephine Baker and Marlene Dietrich.

Leave it to Brad and Angie to give the kids a history lesson while on vacation!

In fact, he has no idea who the 16-year-old pop phenom is! Check out his hilarious interview clip above, where the metal god was being interviewed by Blink 182's Mark Hoppus...

Last night we spotted Christina Aguilera out and about in London, and noticeably absent was the Burlesque star's new boyfriend, Matthew Rutler. Maybe she left him behind at the hotel for a girls' night out? Can he even keep up with her?

After her strip tease on the X Factor over the weekend, I'm not so sure! Check it out:
