The Voice Justin Bieber Performance - H 2012

Cue the teenage banshee howls: Justin Bieber unleashed his newly smoldering presence on The Voice finale Tuesday night, drawing screams from the audience and smiles from show mentors Christina Aguilera and Adam Levine.

(Come to think of it, Levine -- who has a sardonic streak -- might have been laughing at the 18-year-old's efforts to adopt a decidedly more mature swagger. Aguilera, however, nodded approvingly.)

Back to The Biebs: taking cues from his pop-R&B guide, Usher, Bieber showed off stylized, sexually-charged (pretend we didn't write that) dance moves during a performance of his latest single, "Boyfriend." A far cry from his debut hit "Baby," the song includes such marginally more grown-up lyrics as: "If I was your boyfriend/I'd never let you go/ I can take you places you ain't never seen before/Baby take a chance or you'll never know/ I got money in my hands that I'd really like to blow."

The pop star also took on a Michael Jackson vibe, sporting a black leather jacket with gold studs, but with oversized gold sneakers and oddly swept-over, '90s mall bangs. At one point in his performance, he grabbed his crotch, gesturing toward one of several sexy backup dancers on stage.
