The Baby singer surprised 150 girls and boys at a youth club in Los Angeles

Justin Bieber has turned Santa Claus by spending thousands to give presents out to some of his fans in America.

Ahead of the release of his new film Believe this Christmas, Bieber surprised 150 girls and boys from a youth club in Los Angeles who had a special screening of the film on Monday.

Bieber was seen handing out gifts to the excited kids before sitting down and watching the film.

A source close to the Canadian singing superstar said: “Justin interrupted the movie to tell them he wanted to bring them something to kick-start their Christmas. He stood on stage and gave them toys he brought then sang two songs, including Christmas Love.

“When he was done, instead of leaving, he sat amongst the crowd and watched the rest of the movie. Everyone was super happy and didn’t know whether to watch the film or look over at Justin. It was an early Christmas present they won’t forget and a side to Justin a lot of people don’t always see.”
