Justin Bieber wants Lil' Wayne to appear on his second album.

The Canadian 'Baby' singer is planning to collaborate with more rappers on his second album - which he hopes to release next year - and has already confirmed Drake, but is also hoping to lay down a track with Wayne.

Justin told MTV: "The album will probably come out toward the end of next year.

"Drake is gonna be on that album. I'm not sure who else, but I'm gonna ask him if he can get Lil' Wayne on there."

Lil' Wayne is one of the biggest rap stars in the US, but currently serving jail time in New York after a gun was found on his tourbus.

Teen sensation Justin, 16 - who is presently touring the US - also said he hasn't got time for girlfriends, because he's always moving from one city to another.

He said: "I mean, girlfriends are trouble at this age. Girls are fun to hang out with but, like, we're constantly travelling and one girl's not gonna really work. You can't really have one girl. I don't really have any crushes at the moment."
