Will Smith and Gary Barlow perform 'Fresh Prince' theme

Actor and (former) rapper Will Smith performed the theme tune to his eternally popular TV hit 'The Fresh Prince Of Bel Air' on Graham Norton. Watch the clip below.

Joined by Take That frontman Gary Barlow, Smith rapped the unforgettable theme tune on UK TV. Norton presented Barlow with a keyboard to accompany Smith. "You've probably seen some musicians before - but get ready my friend," said Gary Barlow before Smith, along with an entire studio audience, rapped the track. Watch the performance:

However, this clip isn't the only Will Smith video doing the round this weekend, as a video of the actor slapping a journalist on the red carpet at the Ukrainian premiere of his movie 'Men In Black III' after he attempted to land a double-kiss on the actor - who mistook the gesture as something more dubious. He responded by slapping the shocked man. Watch below:
