Justin Bieber is set to release his second studio album 'Believe' on 19th June.

Meanwhile, Justin's labelmate Carly Rae Jepsen has spoken to Capital FM about her new collaboration with the star.

"Justin and I worked on a duet together the first day that we met, so there's potential for that song. Although nothing's been set in stone at this point," she said.

"It's kind of just a really chilled song actually," Carly teased. "He wrote it, so all the credit for its writing goes to him, but I guess you'll have to wait and see!"
