Depp has Bieber fever

The actor is spotted at teen's gig in Miami

Johnny Depp was spotted at a Justin Bieber gig on Saturday.

The actor was seen in the crowd, before Bieber said to the audience "Johnny Depp wants to hear 'Baby'", referring to his popular single.

The Pirates Of The Caribbean actor was later seen leaving through the backstage door. 

It's not been confirmed why Depp was in Florida or whether he'd attended the gig with his children.
