When Rihanna says "Cheers (Drink To That)," she's not kidding!

The Barbadian beauty took a cue from her latest single, downing liquor while vacationing on a yacht in the French Riviera Monday.

Not afraid to show some skin, Ri even tossed aside her black oversized Bob Marley tee during the day to reveal a bold cut-out bathing suit.

Not only that, the singer decided to go au naturel while on vacay! She emerged on one of the decks with wild brown curls - not the bright red locks she's been sporting for months - and no makeup.

Rihanna is sandwiching this vacation in-between two big performances - she appeared at the V Festival in England this past weekend and will debut "Fly" with Nicki Minaj at the 2011 MTV Video Music Awards pre-show Sunday, August 28.
