Justin Bieber debuts new song shirtless

Los Angeles - Justin Bieber unveiled a new song, You Want Me, on Sunday.

The Beauty and a Beat singer was scheduled to have a live chat with fans on Sunday, but couldn't get a good internet connection as he is currently on holiday, so instead posted a video and a preview of the unfinished new song.

The singer appeared shirtless in the clip and apologised, saying: "My fans are just overpopulating the sites and I just don't think it's going to work. So I'm just going to make a video and play some new music."

He later posted a link to a version of new mid-tempo track You Want Me, saying: "Its not finished but here's a little part a song I'm working on."

A number of challenges

Words to the track include: "I can take you to a new world/ Take your problems away/ Tell me what you want to do girl/ Just come right this way."

Meanwhile Justin 18, apologised for "smoking weed" in a skit shown on Saturday Night Live in the US on Saturday.

Justin has faced a number of challenges recently including the breakdown of his on/off relationship with Selena Gomez at the beginning of this year, including the accidental death of a paparazzo who was taking pictures of the Beauty And A Beat singer's car.

He was also recently forced to defend himself when he was accused of being out of control after being pulled over by police, but insists he is a "responsible" teenager.
