Sexy Stars in the Shower ... Guess the Georgia Peach!

Who's feelin' thirsty for Thirsty Thursday?! We've got quite the thirst trap for you, but you gotta guess which sexy star put her summer bod on full display in this eye-popping shower shot ...

She's a best-selling author who's business savvy -- ie: her hair and beauty lines. You may not be able to see her face in this shot, but you've probably seen it on 'Housewives.'
