WHO: Singing senstation, Rihanna
WHAT: RiRi attended a formal, yet fun event in a look very similar to the one she wore to this year's Grammy Awards. She slipped on a sexy, deep green gown with a thigh-high slit and deep V's in the back and front that left little to the imagination. To accessorize, the songstress added strappy metallic sandals and a gold statement necklace.
WHERE: Stella McCartney's winter 2012 Evening Wear Presentation In London on February 18th.
