Will Smith loves a chat show sing-along doesn't he?
He just can't help himself, whether it's the Fresh Prince… theme or in this case 'Summertime', he's whipping out the mic at the first opportunity.
Smith performed the 1991 hit on Jimmy Kimmel Live! with DJ Jazzy Jeff joining in via webcam.
The actor and rapper also recreated the theme tune to The Fresh Prince of Bel-Air while appearing on Ellen.
Smith previously performed the tune on The Graham Norton Show, complete with Jazzy Jeff, son Jaden Smith and Alfonso Ribeiro doing the Carlton dance.
