A Fresh Prince reunion happened on “The Graham Norton Show” on Friday night.

The Fresh Prince of Bel-Air staged an impromptu reunion after Will Smith, who has gone on to break through as an acting superstar and proud papa, watched his son Jaden at the mic.

The Men In Black star told Norton, "Last time I was here I did my Fresh Prince rap - eight million YouTube hits was on that. This time I brought my DJ Jazzy Jeff."

Will Smith then hit the stage to bring his old partner DJ Jazzy Jeff up. Will and Jaden Smith treated the audience to a performance of the Fresh Prince theme songs.

At the end of the performance Smith asked, "You like that? Well hold up Graham my man I'm not through - one more little surprise just for you."

Alfonos Ribeiro hopped on stage to lead the father-son duo in the Carlton dance. Ribeiro played Smith’s cousin Carlton on the TV show “The Fresh Prince of Bel-Air.”

Unable to contain himself, Graham Norton joined the trio in a dance-off to the classic "Jump On It" by The Sugarhill Gang while Heather Graham ground on the couch.

Will Smith was in London with his son Jason to promote their upcoming science fiction picture "After Earth." During the “Graham Norton Show” appearance Will teased Jason about his rap skills and Norton urged the two to throw down. At the end of the reunion performance Smith said, "Just a little treat for you."

At the end of the show, Norton exclaimed, "That is so cool! What a treat that was."

The performance has already pulled over 8 million YouTube hits.

While Smith was in London he went to see his eldest son Trey, a DJ just like his dad, perform at a local club, where he was joined by his costars, and to attend a few London events with son Jaden.
