Graham Norton had a star studded sofa last night, but they paled into insignificance when Will Smith, Alfonso Ribeiro and DJ Jazzy Jeff teamed up for a bit of a Fresh Prince of Bel Air reunion.

Heather Graham and Bradley Cooper became audience members as Will and son Jaden took to the floor to give the crowd a rousing rendition of Will's 'Switch' with the assistance of DJ Jazzy Jeff. However, the fun didn't end there, with Will pulling old pal Alfonso Ribeiro up to get jiggy with it, and our Graham even getting in on the action. We loved it, and so did Twitter: Our feed exploded.

We're sure we'll be playing this one back for quite a while. Touche Mr Norton, we tip our hats.
