The 17-year-old pop star is friends with Brooklyn, Romeo and Cruz Beckham after meeting them at one of his shows last year.
He said he would travel to their LA home to put on a show for the whole family and might even bring his girlfriend Selena Gomez.
Bieber said to UK's Closer magazine: '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. Maybe now they have a girl, Selena will have to come too, and dedicate a song to Harper.
'David tells me my records are always played in their household, and David and Victoria are both really cool, so I'm happy to oblige.'
