Television audiences in the U.K. were treated to a special surprise when Will Smith and his son, Jaden appeared on the popular talk fest, 'The Graham Norton Show.'

The veteran rapper reunited with his longtime music partner DJ Jazzy Jeff and actor Alfonso Ribeiro of 'The Fresh Prince of Bel Air.'

The set-up was perfect. During their interview with host Graham Norton, the Smiths were asked about collaborating on a song together. Will responded that they do have an in-home studio but they've never really done any collaborations. "He's a very good rapper though," said Will of Jaden.

Norton then persuaded the dynamic duo to bust a freestyle on the microphone for the audience and they obliged him.

What happened next is pure television excellence and, might we say, the best hip-hop moment of 2013.

Will grabbed the mic and preceded to beat-box while Jaden rapped a carefree rhyme. "Hello, my name is Jaden / And I'm a young fellow / I like to keep it mellow," he raps.

Next, Will dropped another surprise -- DJ Jazzy Jeff on the turntables for a club-style rendition of his ever-popular theme song to 'The Fresh Prince of Bel-Air.'

Will and Jaden's performance was so turnt up even couch guest Heather Graham was shaking her blonde hair uncontrollably.

Then, he invited fellow 'Bel-Air' co-star Ribeiro (aka Carlton Banks) onstage for special dance renditions of Tom Jones' 'It's Not Unusual' and the Sugarhill Gang's 'Hey Apache.'

Thankfully, you can watch the now-viral video repeatedly for your enjoyment. Full disclosure: we have watched it over a hundred times and it keeps getting better and better.

As of this writing, the video has garnered over 13 million views so far and counting.
