The pint-sized pop star would ordinarily be much too short to play in the basketball league but he showed that he was not intimidated by the game held at the Los Angeles Convention Center.
Bieber was representing the West team which was coached by Magic Johnson and managed by Jimmy Kimmel.
Little and large: Justin who is 5' 5" was dwarfed by basketball legend Magic Johnson who is a towering 6' 9"
At 5' 5", Justin was a lot shorter of many of the other players, especially his NBA legend coach who is a towering 6' 9".
Bieber's West team lost 49-54 to the East Conference side but the Baby singer was still honoured for scoring eight points, two rebounds and four assists.
In his red jersey and yellow sneakers, the teen sensation looked even younger than his 16 years. When receiving his trophy, Bieber screamed: 'We're going to Disneyland'.
Bieber's team members were reality star Rob Kardashian, Chuck star Zachary Levi, rapper Common, Modern Family actor Ty Burrell, actor Jason
Alexander and rapper Lil' Romeo.
Bieber will be kicking himself though as he missed a 3-pointer with 30 seconds to go that would have tied the game.
But the singer had made a tiring 13 hour plane journey to get to the game and went straight to the court when he landed.
He later tweeted: 'That was fun. Crazy being coached by @magicjohnson - gonna auction off my jersey for charity at www.bieberfever.com'.
Hall of Fame player Scottie Pippen scored the most points leading the Eastern Conference team to victory. The defensive highlight was Pippen's third-quarter block of Bieber.
But at least the Never Say Never star had a trophy to take home after being left disappointed at last week's Grammys when he failed to win any awards.
