Fergie's Sexy Bikini Vacation Photo Causes a Stir on Twitter

Fergie is the talk of Twitter thanks to a racy bikini photo she sent out earlier this week.

The 37-year-old spent Memorial Day weekend with her husband Josh Duhamel on a hot beach in Mexico. Her timeline exploded when she twitpic'd a full body shot of herself wearing a multicolored 2-piece.

"¡Adiós Cancún!" she wrote before heading back to the States.
