Justin Bieber unveiled a new song, 'You Want Me', last night (10.02.13).

The 'Beauty and a Beat' singer was scheduled to have a live chat with fans last night, 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.''

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 (09.02.13).

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.
