Canadian pop star Justin Bieber has teamed with country sensation Taylor Swift on a new song for his upcoming third album ‘Believe’, though details were scant as the ‘Boyfriend’ singer keeps fans guessing. Shrieking at this point is totally okay. Bieber told a British radio station in a recent interview that Swift was one of several people he had worked with on ‘Believe’. “We worked with Mike Posner for ‘Boyfriend,’ so that turned out well,” he told a radio station. “It’s crazy. I mean, I even wrote a song with Taylor Swift, so the whole album ranges differently. With my music it doesn’t only stay in a box. Everything is so different and that’s why I’m so happy with this album,” he added. Bieber, 18, did not give the title of the song he wrote with Swift, 22, nor did he say if the pair would sing it together. JB has also hinted at wanting to do something with Adam Levine. “I think we need to do something on @NBCTheVoice,” he tweeted to the show coach. And continued with some upcoming news, “Next Tues @nbcthevoice Im gonna WORLD PREMIERE the first clip of the #BOYFRIENDvideo. Might also announce some major #BELIEVE news too.” ‘Believe’ is expected to drop this summer and will also include the musical sounds of Drake, Kanye West, Timbaland, Usher and Diplo.
