Out of the blue, we get a new version of Beyoncé's song "Jealous" today, which now features an appearance from Chris Brown. No word on when this version was recorded or where it was intended to end up, but the duet sounds rather good with Bey and Breezy going back and forth on the energetic track. The original version was featured on Beyoncé's 2013 self-titled album, but you can hear the new duet below.
