Hear Chris Brown and Rihanna Reunite on Previously Unreleased Track "Put It Up"

There was a time when Chris Brown and Rihanna made beautiful music together. We thought that time was over, until someone leaked "Put It Up" — the duo's newest collaboration that was supposedly slated for C Breezy's X album, but never actually made the cut.

We're not sure when C Breezy and RiRi recorded the track, but the lyrics suggest that they made it when they were still a couple. "I'm in love," they admit to each other over and over again. "I'mma give you all of my love, and I hope that you won't misplace it," Rihanna sings. "You're the only one I wanna stay on the phone with," Chris responds, adding in a line about Skype sex.

A lot has happened since these two parted ways. For Chris, there was Karrueche, and then there was baby Royalty. Rihanna keeps surprising us musically, and though we're still waiting for R8 to drop, we've got "American Oxygen" on replay in the meantime.

Hear RiRi perform "Bitch Better Have My Money" at the iHeartRadio Music Awards in the clip.
