Justin has confirmed something really exciting about his upcoming album, Believe: He teamed up with Taylor Swift to write one of the songs for it! That’s right, JB confirmed in a radio interview today that Tay is one of the famous faces he worked with on the album. “It’s crazy. I mean, I even wrote a song with Taylor Swift, so the whole album ranges differently,” he said.

We wonder if that means Tay sings with Justin, or if she was strictly behind-the-scenes? Either way, we can’t wait to hear the track. What do you think about Taylor and Justin teaming up on a song? Sound off in the comments and on Twitter!
