Rihanna and Chris Brown are collaborating on another song.

The former couple most recently teamed up on 'Nobody's Business' - a track from Rihanna's latest album, 'Unapologetic.'

After being spotted leaving a Los Angeles recording studio on Thursday night, Brown's representative confirmed to E! News that a new collaboration is in the works.

No further details about the upcoming track have been released, however R&B star Brown is set to release a new album this year so it is a possibility Rihanna is lending vocals to one of his songs.

Rihanna addressed the pair's most recent duet in an interview with Complex magazine.

When asked about the track, she responded: "Pardon me? It's the truth. Remember? It's a fun record that The Dream wrote and we loved the lyrics."

She is also quoted as saying "you're still asking me questions about it so clearly you don't know," at the end of the chat.

The pair - who hit headlines in 2009 after Brown was charged with assaulting the stunning singer - also joined forces on remixes of Rihanna's 'Birthday Cake' and Brown's 'Turn Up the Music.'
