It's official! These two have been making sweet, sweet music again!

On-and-off again couple Chris Brown and Rihanna are currently busy in the studio recording their fourth duet together.

After the pair were spotted leaving a recording studio separately in Hollywood on Jan. 17, Chris' rep confirmed to E! News that the singers are collaborating, yet again.

Their new tune comes on the heels of the duo's recent single, "Nobody’s Business," a track on the 24-year-old songstress’ most recent album, Unapologetic.

Nearly a year ago, for the first time since Chris assaulted Rihanna in 2009, the former flames shocked the world by releasing remixes of her hit “Birthday Cake” and Chris’ tune “Turn Up the Music,” but that was only the beginning.

In November, the “Diamonds” singer confirmed that she and Chris were “not together,” but that she considers him “dope.” Since then, the pair have taken several snapshots together, which they've plastered on twitter, which leaves fans wondering if they've rekindled their romance.

And so the mystery of their relationship continues. But by the looks of their constant photo uploading and sightings together — plus the cover of her new single which apparently shows her sucking on Chris’ neck — we think they’re on pretty good terms.

Since it's looking like Chris and RiRi are back on, do you think they're ready to give love a second chance?
