Joy Corrigan won't be held back by anything when she's on the job -- especially not a silly bikini top.
The S.I. swimsuit model was doing a photo shoot in Miami, and ditched the top half of her bikini just because ... and the view -- front and back -- seemed to be working from the photog's point of view.
Joy's no stranger to Florida shoots ... she pulled a Baywatch look last summer, where things got pretty messy on the beach.
Tough job. We're glad she's doing it.
