Usher tells Britain's Daily Mirror, "David's a good friend of mine. I got a call from him about two months ago and we were catching up. One of the things we talked about was that he wanted his sons to have dance lessons.
"He wanted to start them off in Los Angeles and I said that I'd help. He thought it would be fun for them. It would be good to catch up with them, they're such a pleasant family."
