Former couple Rihanna and Chris Brown have teamed up to work on remixes of each other's tracks.

The pair, who dated up until Brown assaulted the Bajan star back in 2009, confirmed the news on their Twitter pages, after much speculation.

Rihanna, who celebrated her 24th birthday on 20 February, revealed that she'd worked with Brown on a remix of her track, Birthday Cake, while Brown enlisted the We Found Love singer's help on a remix of his new single, Turn Up the Music.

Brown, 22, wished Rihanna a happy birthday yesterday via Twitter, alongside a link to the Cake remix. Rihanna then repaid the favour, posting:

"Turn up the music remix #RihannaNavy #Teambreezy enjoy!!!

"Its a download OVERLOAD!!!! Working on more links for u guys, so errbody could have some #CAKE" [sic]

Earlier this month, Brown - who's also referred to as Breezy - was told that he must remain on supervised probation, following his attack on Rihanna three years ago.
