Justin Bieber returned to his roots by giving an impromptu free performance on the drums at a Hollywood club.

The pop heartthrob was chilling out at the Peppermint Club, when he jumped on stage and stepped behind the drums.

Dressed causally in jeans and a beanie, Justin then gave a surprise show for the stunned club-goers.

It isn’t the first time Justin, 22, has surprised people with a show lately.

In November, he tickled the ivories in an unplanned performance at a piano bar in Toronto.
