Justin Bieber has put on his gloves to test out his own boxing skills - with former champion Mike Tyson as his personal trainer.
The Baby hitmaker stopped by his odd pal's Las Vegas home while in town for the Billboard Music Awards earlier this month and practised his punches on a heavy bag in the retired sportsman's garage.
Footage of the impromptu training session has since been posted on YouTube and the brief video shows Bieber beating up the bag as Tyson offers up words of encouragement and advice.
On the clip, Tyson tells the teenage pop star, "Jab, jab, JB show 'em, get pretty on 'em baby! Put those combinations together... Good move... Good one JB!"
News of Bieber's training with Tyson emerges just a day after he was involved in an alleged scuffle with a paparazzo on Sunday. The singer is wanted for questioning by Los Angeles police after reportedly losing his cool and confronting the snapper after he tried to take pictures of the star and his girlfriend Selena Gomez.
The unidentified photographer was hospitalized and released shortly after receiving treatment for his injuries.
