Eva Mendes and her gorgeous canine companion went for a walk in Hollywood yesterday, and the sexy starlet showed off her assets in a pair of skintight blue yoga pants. Now that's something to bark about!

Finally! The hotel heiress has ditched her classy black ensembles for a bright, colorful dress - and bag! Loves it or hates it?

Kiefer Sutherland turned himself into police in New York City Thursday afternoon where he was given a desk-appearance ticket for allegedly headbutting Proenza Schouler designer Jack McCollough at a party earlier this week.

Wearing an overcoat to protect from a light drizzle and dressed in a light blue button down oxford shirt and blue jeans, Kiefer smiled at the media gathered around as he made his way inside Manhattan's 1st Precinct.

Since he wasn't charged with a felony, the 24 star can travel and will not be held in custody.

Neither Sutherland, nor his attorney made any statements about the charges.

Reese likes short shorts! The Oscar-winner was dropping off son Deacon the other afternoon in a gray tank and jogging shorts. Work it, Witherspoon! She's been looking so fit lately - acting, being a mom, dating a hot hunk... I dunno how she does it all!

And by feeding the homeless, I mean giving them a mouthful of her funbags!

The busty porn star got dinner at Katsuya last night, and after her meal she decided to give a local homeless man a show he'll never forget. I guess this makes her some sort of good samaritan?

Gwyneth Paltrow typically hides her face from the paps, but not yesterday! Again we spotted the Iron Man starlet with her son Moses at school. Usually I don't like the long-haired look on baby boys, but M really rocks it! Take note, Ryder.

Last night, Katy Perry celebrated the premiere of her new music video, "Waking Up in Vegas," at Mr. West nightclub in NYC, and it looks like the singer had a blast!

Katy's on again/off again boyfriend, Travis McCoy showed up, as well as Rihanna and a mini-Katy Perry from Jeff Beacher's Madhouse. Katy spent time chatting with her lookalike, and the ladies posed for photos and partied the night away. Rihanna, Travis and Katy hung out at their VIP table and drank Svedka vodka until the wee hours of the morning, occasionally taking breaks to snap pictures and dance. Sound like a great party to us!

Even though Cam Gigandet's O.C. character killed Marissa (aka Mischa Barton), I'll forgive him because he and his girlfriend Dominique are sooooo damn attractive.

We spotted the happy couple taking their newborn baby Everleigh out for a stroll in LA. You know that girl is gonna be a looker!
