Demi Lovato posted a series of hot, hot, hot bikini pics while on a birthday trip to the Maldives with friends. The singer wears an almost sheer white one piece by LA based swimwear brand, Frankies Bikinis. After recently releasing new music, they seem to be truly glowing while enjoying their time on a beautiful island. Demi poses in the Charlotte One Piece in white; a classic, figure-flattering style.
