Ed Sheeran loves a collaboration! And now he's added Chris Brown to his ever-growing list.

However, this was one performance with a difference. The collaboration took place live in a Las Vegas nightclub!

Ed dropped by for Brown's performance at Drai's nightclub on Sunday night to perform on his track 'Loyal', which Sheeran has been known to previously mash-up with his own hit 'Don't' whilst on tour.

The duo teased the audience with an a cappella version, but later decided to go for it and perform the whole track with Ed taking over Lil Wayne's part. Luckily one starstruck fan managed to film the occasion and upload the duet.

In addition to 'Loyal', Sheeran sang 'Thinking Out Loud' to a packed audience whilst other special surprise guests, Nelly, Trey Songz and Jeremih, danced along in the background.

During the same weekend, Ed was spotted partying with Calvin Harris and his rumoured-to-be new girlfriend!
