Forget parties and the Hollywood scene -- Paris Hilton knows that the best way to spend her down time is with her sister Nicky!

Paris and Nicky caught a screening of Megamind at the Grove in Los Angeles last night, and as always, both of the ladies were super sweet to photogs as they headed back to the parking garage. So what did Miss P think of the movie? She tweeted, "MEGAMIND was such a great movie! 3D is deinitely the future! Had an amazing cast, so funny! A movie for both kids and adults! :)"

I suppose that's the best way for a happily married couple to split things up!

While Jennifer Garner and Seraphina were horsing around at a barn in Los Angeles, Ben Affleck was snapped running errands with the couple's nearly five-year-old daughter Violet. Now that Jen seems to have given up on carrying Violet, it makes perfect sense that she's hitting up her dad! After all, Ben's 6'2" and pretty buff, so it's not like it's breaking his back!

Over the weekend Gwen Stefani was snapped returning home to her Brentwood pad, and look who was there to greet her! The Halloween festivities may have ended last Sunday, but clearly in the Stefani-Rossdale household, costumes are just another form of self expression and style. Kingston = cutest kitty ever!

On Saturday afternoon Halle Berry and her steady boyfriend/Dark Tide co-star Olivier Martinez brunched at Maison Richard Restaurant & Bakery, and later we snapped the couple dropping by the Libertad sunglasses store on Melrose.

But where was little Nahla? Think Olivier has what it takes to be a doting stepdaddy?

Former Victoria's Secret model Heidi Klum was snapped out and about in cargo pants and Converse sneakers on Saturday, but even with this totally casual outfit she still looked like a million bucks! The mother of four may not be making an appearance at the annual VS fashion show on November 30, but there will be plenty of other angels to entertain us...

Is she ready for her comeback?

A noticeably thinner Mischa Barton stepped out for a shopping spree on Robertson Blvd in West Hollywood yesterday, and the actress attracted a ton of attention as she tried to slip back into her car. Mischa brought her dog along with her, and even though we're not digging the bold print top she's rocking, she definitely looks like she's been spending time at the gym and eating healthy! Maybe a decent acting role is next?

Rihanna will always be a stunner, but the Raggedy Ann hair color she's been rocking since June is getting about as old as a jack-o-lantern on the front porch right now...

Sandra Bullock was spotted boarding a bus in New Jersey after leaving Manhattan on Saturday, but this wasn't exactly a Greyhound! Sandy hopped on a private vehicle with tinted windows and several staffers, and we're guessing there were plenty of amenities for the Oscar winning actress and her son Louis.
