Bieber tells Britain'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 ... 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."
