Bieber at the Beckhams'

The teen heartthrob agrees to sing for their children in return for a favour from David.

Brooklyn, Romeo and Cruz Beckham are known to be fans of Justin and the 'Baby' star has offered to give them a private concert, albeit on one condition:

"I’ve agreed to give the boys a private concert at their house – if David gives me some private soccer lessons! David’s an amazing dad, and he told me how happy it would make the boys, so I had to say yes."

Justin also suggested that he could be bringing a friend along:

"Maybe now they have a girl, Selena (Gomez) will have to come too, and dedicate a song to Harper."

The secret gig offer came about after Usher’s protégé heard that the Beckhams were big 'Beliebers'.

"David tells me my records are always played in their household," he told Closer magazine. David and Victoria are both really cool, so I’m happy to oblige."
