From East Coast to West, stars hit the town on Monday dressed in the best and worst fashions, and Breaking Celebrity News has all the photos to prove it!

2010 was clearly a smashing year in fashion for the stunning Blake Lively, and it seems as though the Gossip Girl plans on finishing the year off in high style. The newly single star hit the launch party for Lorraine Schwartz 2BHAPPY Jewelry in NYC taking our breath away by pouring her bombshell bod into a corseted Versace Spring 2011 dress, which she paired with Christian Louboutin platforms and Lorraine Schwartz jewels.

Other style savvy guests included Beyonce, who looked white hot in an Antonio Berardi pencil dress and Cesare Paciotti sandals, Ashanti who popped in a hot pink NOTTE by Marchesa mini and Kim Kardashian, who flopped by wearing matte black tights with her chic Versus party dress.

Sharon Stone was in blinding style, while dining at Mr. Chow in Beverly Hills. Leaving her Basic Instinct at home, the stunning star wore a neon yellow bandage mini with black nylons, boots, a sweater and an Emilio Pucci scarf.
