"I'm wearing Narciso of course!" exclaimed Jessica Alba, who posed with Emmy Rossum (also in Narciso) backstage at the Narciso Rodriguez show. Alba's favorite look from the collection? "Oh god I have so many favorites-the black leather coat, the shape is amazing, and the little pink dress."

With matching long blond locks and black eyeliner, Lindsay Lohan and Gossip Girl's youngest star, Taylor Momsen, checked out G-Star's latest collection-which included several white-denim looks-at the Hammerstein Ballroom.

Known to wear Rodarte on the red carpet, Kirsten Dunst supported designers Kate and Laura Mulleavy by taking a front row seat at their Spring 2010 fashion show.

Glamming up the front row in all-black ensembles at the Badgley Mischka show were Fashion Week-regulars Kim Kardashian and Kelly Rowland. The two didn't show signs of slowing down either. Kardashian also stopped by Malandrino and Baby Phat, while Rowland hit Max Azria and Brian Reyes.

Elizabeth and James designer Mary-Kate Olsen joined art-loving stars like Josh Hartnett, Alicia Keys and Nicky Hilton at the opening of the Richard Hambleton-New York exhibition, presented by Vladimir Restoin-Roitfeld and Andy Valmorbida in collaboration with Giorgio Armani.

What's black and white and geometric all over? Max Azria's Spring 2010 collection, which was presented at The Tent at Bryant Park. Lucy Liu watched the designs-which Azria called "quiet and relaxed, but very strong"-from the front row.

Small-screen beauties Katrina Bowden and Ashley Madekwe, who attended Max Azria's shows earlier this week, continued their support for the designer by attending a dinner hosted by him and his wife, Lubov.
