Justin Bieber was challenged by NBA star Shaquille O'Neal to a game of basketball and will wish he hadn't, after he lost to the 16-year-old singer!

At 7ft 1ins tall, the NBA star is over 2ft taller than 5ft 4ins Justin, but this made no difference to the One Time star who beat Shaquille on his own, private basketball court.

The basketball game was one of the challenges for Shaquille's US TV show, Shaq Vs. which sees the star take on various celebrities at whatever they do best.

The other challenges the pair took part in included a dance-off, staying underwater for longest and the show even sees Shaq join JB on stage for his Florida concert!

We love seeing how small Justin looks next to the basketball player. So cute!
