Yesterday in Florida, falsetto-lover Jason Derulo appeared onstage at Mackapooloza. He started off his performance in a black tank top that accentuated his toned shoulders and large biceps and what appeared to be camo-printed pants made out of snakeskin. But over the course of his set, Derulo transformed into a slick, shiny specimen of man (we thank the humidity) that looked like he'd been dipped into a pool of grease. This all built up for his finale: the moment, where in a fit of heat and performance passion (we're guessing), Derulo tore off his tank with his two bare hands, unleashing his torso to his screaming fans. He never looked more pleased.
