Sexy Black Dress Style Showdown: Rihanna vs. Gwyneth Paltrow (POLL)

Two sexy ladies, one sexy look!

Rihanna and Gwyneth Paltrow posed for a quick pic backstage (which Gwyneth posted on her WhoSay page) at Sunday’s Grammy Awards, and were both oozing sex appeal in similar black dresses. Both looks were basically backless but while Rihanna’s showed a bit more cleavage, Gwyneth was showing just a bit of sideboob.
