Justin Bieber has agreed to perform a private concert for the three little Beckham boys in exchange for soccer lessons from their dad, David Beckham. The pint-sized pop star is even considering asking his girlfriend, Selena Gomez, to join him for the event, so she can perform a tribute for brand-new baby Harper Seven. That's a pretty extravagant treat for someone that hasn't mastered the art of sitting up on her own, but I guess why not? It's not like Harper Seven will grow up to be spoiled or anything. There's no way.
