Will Smith and his former collaborator DJ Jazzy Jeff reunited for a one-off performance of their biggest hit Summertime at the weekend.

Big Willy took to the stage at the Las Vegas Palms Casino Resort pool party - and it was a case of "sun's out, guns out" for the Hollywood star.

DJ Jazzy Jeff & The Fresh Prince had an international hit with the track back in 1991.

And more than 20 years on the 45-year-old star proved he's still in great shape - physically and performance-wise - by whipping off his top after he had whipped the crowd into a frenzy.

Fortunately, US gossip site TMZ has obtained footage of the event and uploaded it to YouTube.
