Newlywed Scarlett Johansson dons all-white again, this time at the Michael J. Fox Foundation's benefit, A Funny Thing Happened on the Way to Cure Parkinson's. Last weekend, her husband Ryan Reynolds raised over $80,000 for Parkinson's research with his run at the New York marathon.

Man of the evening Michael J. Fox and his wife, Tracy Pollan, attend the benefit for his foundation. Fox was diagnosed with Parkinson's in 1991 and went public with it in 1998, after which he set out to support increased research of the disease.

Even when she's bundled up on a chilly, New York day, Lindsay Price manages to be alluring. She and Andrew McCarthy were on location in Brooklyn for Lipstick Jungle, which continues to steam up screens on Friday nights

Jane Krakowski puts on her own Girly Show for the photogs, rocking a little black dress at the 2008 Stand Up For Heroes: A Benefit for the Bob Woodruff Foundation.

Jessica Alba and Chris Messina stroll on location for their forthcoming movie, An Invisible Sign of My Own.

Did Gwyneth Paltrow take sexy pills this year? Has she discovered a new stylist? Or is this the dazzling confidence of a mom in her mid-thirties, ready to flaunt every fiber of what she's got? We're not sure exactly why Gwynny has been burning up red carpets lately (like this one for the Paris premiere of Two Lovers), we just hope it inspires another Coldplay album.

While Paltrow reigns over the A-lister carpet scene, Chloe Sevigny still has our indie-flick-loving, Brooklyn-dwelling, hipster hearts on lockdown. The avant garde fashionista threw fall colors to the wind in a powder-blue frock at the 12th Annual ACE Awards at Cipriani.

Sharon Osbourne may be keeping busy these days with Bret Michaels groupies on VH1, but she took a break to support her man. Ozzy was crowned "Living Legend" at the Classic Rock Roll of Honour in London, where Guns N' Roses alum Slash fittingly presented him with the award.

Mark Ruffalo and his wife, Sunrise Coigney, work the carpet at the AFI Film Festival's screening of The Brothers Bloom in Hollywood. Ruffalo stars in the new flick alongside Adrien Brody and Rachel Weisz.

Hayden Panettiere finds her inner diva with ruby-red lips and a vampy gown at the 5th Annual Alfred Mann Foundation Innovation & Inspiration Gala.

Melina Kanakaredes goes for something blue to celebrate CSI: NY's 100th episode. The actress, who's known as Detective Stella Bonasera among her fellow CSIers, proves she can rock a carpet as well as she can crack a case.

Sporting an awesomely bright pink dress at the Hollywood Legacy Awards, Dania Ramirez reminds us why we wear sunglasses at night. It's refreshing to see the Heroes actress (Maya) using her superpowers for fashion, instead of those killer tears.
