Ariana Grande announces duet with Justin Bieber...

Ariana Grande has recorded a duet with Justin Bieber, and it's set to appear on her sophomore album, due in August. Bieber posted an Instagram photo of him in the studio with the Nickelodeon star. I don't rate the Biebz as a singer although some of his records aren't half bad. He's popular, so a duet between them would do well. Since her duet with Chris Brown won't be coming out anytime soon, this new collaboration would be the better bet.

Ariana's new album will feature production from Zedd, Benny Blanco, Ryan Tedder, Key Wane, and Rodney Jerkins.
