Rihanna & Chris Brown Back in the Studio Together

Rihanna and Chris Brown hit the studio together, spawning rumors of new collaboration.

The couple were spotted leaving a West Hollywood studio on Thursday, and rep confirmed to E! News that the two are indeed currently working on another single. So far the two have collaborated on a handful of tracks -- “Nobody’s Business” off RiRi'sUnapologetic, her remix to "Birthday Cake," and the remix to Breezy's “Turn Up the Music" -- since rekindling their romance last year. Rihanna also made a photo of herself cuddling up to Brown the cover art for her most recent Unapologetic single, "Stay."

No word on where the rumored track will surface. Brown is currently working on the follow-up to 2012's Fortune, titled Carpe Diem. Both pop artists follow a rigourous one-album-a-year release schedule, so it could wind up on either singer's next LP. Only time will tell.
