CHRIS Brown has been partying it up on the Gold Coast ahead of the Supafest music festival today.

THE Grammy Award-winner stripped off during a wild night out at Sin City nightclub with fellow R'n'B star T-Pain and girlfriend Karrueche Tran.

The crowd reportedly went crazy when the 22-year-old showed off his buff figure.

Brown's entourage also joined in on the party, along with rappers Naughty By Nature who celebrated across the strip at Shooters nightclub.

T-Pain didn't seem too impressed to share the spotlight with Brown as he kept to himself in the Sin City VIP area.

The stars are in town for Supafest which kicks off in Brisbane today.

Brown and Tran were seen out shopping at Culture Kings on Friday with the singer mobbed by a largely female crowd outside the store.

Former Destiny's Child member Kelly Rowland was also seen shopping at Rebel Sport.

Brown's ex-girlfriend Rihanna - who he was charged with assaulting in 2009 - has denied rumours that she will be making a surprise appearance on stage with him at today's event.
