Justin Bieber, is that you?!
The 21-year-old pop star went goth for his performance of Ozzy Osbourne's classic "Crazy Train" on Spike's Lip Sync Battle.
Not even a week after his Comedy Central Roast aired, Bieber slathered on the guy-liner and nailed his impression of the Prince of Darkness, mannerisms and all.
Bieber did have a leg up on the competition. The "Baby" singer had already worked with the heavy metal rocker in a 2011 Super Bowl ad that featured Kelly Osbourne's 66-year-old father asking, "What's the f**k a Bieber?"
Lip Sync Battle -- airing Thursday nights on Spike -- is becoming a show favorite for all those that loved the celebrity battles on The Tonight Showstarring Jimmy Fallon. In addition to Bieber, Anne Hathaway killed her rendition of Miley Cyrus' "Wrecking Ball." Check it out, below.
