Justin Bieber has teamed up with songwriting superstar Taylor Swift for his upcoming third album, Believe.

The pop star gave Vodafone Big Top 40 an inside scoop on the album.  “You know, the whole album is just so different, there’s so many different people collaborating,” Justin said. “We worked with Mike Posner for ‘Boyfriend‘ so that turned out well, and then we sued Timbaland and Kanye [West] and Drake and so many different people.”

“I even wrote a song with Taylor Swift,” he added.  “So the whole album ranges differently.”  His mentor Usher is also joining the album with a duet.

Justin said that Believe won’t “stay in a box,” revealing that the record will reflect diverse musical genres.

Believe is expected to hit stores this summer.
