Ashanti Shows Off Bikini Bod in Florida Keys Photo Shoot

Ashanti's clearly not waiting for summer to officially start before she shows off her bikini bod -- but unless you're a hardcore stickler for the seasons ... you ain't complaining.

The R&B singer showed off her stunning curves during an incredibly sexy photo shoot in the Florida Keys for a women's fashion line. There were several wardrobe changes as she posed in a series of revealing bikinis on an idyllic beach.

Check out the pics ... if Ashanti doesn't get you in the mood for some fun in the sun -- and hump day, for that matter -- nothing will.

Ashanti wasn't alone. Another model, Leslie Sidora, was working it on the beach, too.
