Will Smith gave fans a treat when he staged an impromptu reunion with a few cast members from The Fresh Prince of Bel-Air during a guest appearance on The Graham Norton Show Friday.

The actor brought along his youngest son, Jaden Smith as hype man, while co-stars Alfonso Ribeiro and DJ Jazzy Jeff joined him on the London stage for some fun.

"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 told Norton in the video below.

Moments later, 'Jazzy Jeff' started the tune as Smith rapped the sitcom's themed-song with Jaden. At the end of the performance the actor said to the crowd, "You like that? Well hold up Graham my man I'm not through - one more little surprise just for you."

Ribeiro, who played Carlton Banks as Will's onscreen cousin appeared on the studio floor, and the trio--Will, Jaden and Ribeiro himself danced on the stage to Tom Jones' It's Not Unusual.

Fans were delighted as the men did the famous dance from the song, in which Norton later joined in for the fun.

After the show, Smith and his family and friends were spotted at the posh eatery Hakkasan and was joined by other celebrity friends, The Sun reported.

Singer Rita Ora and boyfriend Calvin Harris were photographed holding hands as they headed inside the restaurant.

Jaden and Selena Gomez, who is rumored to be Justin Bieber's on and off girlfriend were also spotted entering the eatery together.

Will became famous from the show back in 1990 as an 22-year-old actor and is now one of the most recognized actors on television from the sitcom's six-year, 148-episode run.

Will and Jaden will play as onscreen father and son in After Earth which is scheduled to his theaters on May 31.
