Justin Bieber showed his more grownup side during his performance on the first results show for "Dancing With The Stars: All Stars." Bieber kept his young fans up late on Sept. 25 to offer more crotch-grabbing and gyrating than usual in a head-to-toe leather outifit. He ended his performance with an intense stare into the crowd, it was reminiscent of shows by his mentor Usher and the late Michael Jackson.
