Justin Bieber impersonates Ozzy Osbourne for TV sketch

Justin Bieber dons a black wig and eyeliner to transform into goth rocker Ozzy Osbourne for an upcoming TV comedy sketch.

The Baby hitmaker shed his serious image to impersonate the performance style of the Black Sabbath star for an upcoming episode of comedy series Lip Sync Battle, in which celebrities dress up as a singer and mime to a song.

A promo clip shows Bieber taking on Osbourne's hit Crazy Train while wearing a long, black leather jacket, black clothes and several rings. As he lip syncs to the track, he frequently strokes the front of his black wig and 'sings' through an evil grin while making his eyes bulge out of his head in a creepy fashion.

The date for Bieber's episode has not been released. The inaugural series of Lip Sync Battle aired on Thursday night (02Apr15) with performances by Common, John Legend and Dwayne 'The Rock' Johnson.
