Rihanna and Chris Brown are back together, musically at least. Both artists have released remixes to their latest tracks featuring their other, and here's the second of the singles.

Controversy has trailed the news that the duo were going to reunite musically, but they went ahead to release the remixes, and here's the second, a remix of the 'Cake' track, which featured originally on Rihann's 'Talk That Talk' album.

For Rihanna's latest, both tweeted their excitement about the release. Chris said, "Chris Brown @chrisbrown @rihannagoo.gl/ttRJR YIKES!!! Cake, cake, cake!"; and Rihanna said, "#RihannaNavy Come and put ya name on it!!!!! RT @chrisbrown: @rihannagoo.gl/ttRJR YIKES!!! Cake, cake, cake!"

The remixes, this and the other, 'Turn Up The Music' featuring Rihanna, have been causing a ruckus since their release; but, maybe it's in a good way.
