The "Baby" singer hit the stage at KIIS-FM's Jingle Ball show at the Nokia Theatre in L.A. wearing a sexy black shirt. We couldn't help but notice those bulging muscles. Pump it up, Biebs.
As for Ke$ha, the 25-year-old "Die Young" singer strutted her stuff in a gold leotard and even did a cartwheel. Whoa ... that's a whole lot to look at!
