London:
Teen sensation Justin Bieber has had an impromptu boxing session with British champion David Haye.
The Baby hit maker stepped into the ring with the current World Heavyweight Champion at his training gym in London on Sunday.
David said he was impressed with his 17-year-old opponent's punching skills. He wrote in a post on his Twitter page, "Great workout in The Hayemaker Boxing Gym, Justin Bieber. You sure can pack punch!"
It's not the first time the boxing giant has taken on a pop heavyweight - he sparred with rapper Dizzee Rascal earlier this year.
