Academy Award-winning actor Will Smith appeared on the May 24 episode of British comedy chat show "The Graham Norton Show" with son Jaden Smith to talk about their forthcoming movie "After Earth". But the father-and-son tandem also ended up entertaining the audience as they gamely put on a show after being handed the microphone by host Norton.

After revealing during the interview that they haven't collaborated in music yet, Will and Jaden took the stage to perform a rap number, with the elder Smith beatboxing to his teenage son's rhymes. After the science fiction action flick co-stars delighted everyone on the set, turns out Will had more surprises up his sleeves, as he brought in his hip-hop partner DJ Jazzy Jeff, who went behind the DJ's station as Will dished out the theme song of "The Fresh Prince of Bel-Air", the show that jumpstarted his career.

And as if that wasn't enough to drive the crowd crazy, Will then calls onto the stage his fellow "Fresh Prince" actor Alfonso Ribeiro who played his rich, spoiled cousin Carlton Banks on the TV series. Ribeiro brought the house down with his famous "Carlton dance", the moves he danced along to Tom Jones' "It's Not Unusual".

The mini-reunion culminated in a "Jump On It" dance number by Will and Jaden, Ribeiro and Norton himself who was egged on by Will to dance along. Watching from the interview area were Bradley Cooper and Heather Graham looking amused as the performance unfolded.
