Pop star Justin Bieber stunned diners at a restaurant in Los Angeles on Tuesday night (20Jan15) by performing a surprise show for them.

The Baby hitmaker, who is attempting to make a music comeback after a year of personal problems, bust-ups and legal issues, arrived at the State Social House venue and took to the stage to play an impromptu acoustic set for patrons.

Video footage posted online shows Bieber sitting on a stool, playing a guitar and singing. Reports suggest he performed four songs, including his Cody Simpson collaboration Home To Mama and a cover of Edwin MCCain's I'll Be, before leaving the stage.
