Leona Lewis stole the spotlight in a sparkling Diane von Furstenberg gown during a recent performance with Tony Bennett at the London Palladium.
Rosario Dawson introduced the cobalt creation to the red carpet at the 2011 Vanity Fair Oscar Party back in February.
While both ladies opted for similar shoes, I like how Rosario gave the toga-esque dress more structure by cinching it at the waist, so I'm giving this one to her.
Who stole the spotlight in Diane von Furstenberg?
