Teen pop sensation Justin Bieber, who has just released his new album Believe, says he has collaborated with rapper Lil Wayne on a track called Backpack.

The 18-year-old singer said though the song is not listed in the album but it will likely to be featured in the repackage version of his latest studio installment, reported Ace Showbiz.

"I did a song with Lil Wayne and it's called Backpack, and you guys need to listen to it. It's dope. I wanted a female rapper and I think that she is the best choice. I felt she just fit on the song (Beauty and a Beat) perfectly," he said.
