Who was dressed to rock and shock last week?

From the red carpet of the hottest Hollywood events and movie premieres to the city streets, the world’s most famous celebrities showed off their winning and sinning style and Breaking Celebrity News has all the photos and details in our weekly Best, Worst & Wackiest Dressed fashion feature.

Kristen Stewart may have taken a little hiatus from the red carpet after her shocking cheating scandal, but her Twilight costar Ashley Greene is definitely making up for her absence. After looking flawless at the 2012 Do Something Awards in a Michael Kors Resort 2013 patterned sleeveless number, a Roger Vivier clutch and Giuseppe Zanotti peep-toes, the brunette beauty dropped jaws in feminine fashion at the Los Angeles premiere of The Apparition, in a stunning Donna Karan Atelier pink gown and Jimmy Choo heels.

Other style scores included Serena Williams in Victoria Beckham at The Late Show with David Letterman, Nina Dobrev in GUiSHEM at the celebration of her Ocean Drive magazine cover in Miami and Eva Longoria in Alberta Ferretti at the Global Gift Gala.

Talk about a Fergie fashion flop! The Black Eyed Pea slipped up on the streets of Beverly Hills wearing an unflattering Carven ensemble with a Louis Vuitton and a Goyard bag and platform, sneaker-style shoes.
