The Fresh Prince of Bel Air Reunion on Graham Norton Show

Watch Will Smith's Fresh Prince of Bel-Air Reunion

Now this is the story all about how . . . Will Smith thrilled The Fresh Prince of Bel-Air fans by spontaneously breaking out the show’s rap during a recent appearance on The Graham Norton Show. And even better, he got his son Jaden Smith on the act — they were promoting their movie After Earth and sitting alongside The Hangover Part III’s Bradley Cooper and Heather Graham — as well as his DJ, Jazzy Jeff, and Alfonso Ribeiro, who fans will know as Carlton Banks.

It started with Graham asking the father-son duo about whether they had collaborated on music, and then he produced two microphones after Will praised Jaden’s rapping skills. One Smith family performance later, and Will brought up how he had done the Fresh Prince rap the last time he’d been on the show, and that it had amassed over eight million views on YouTube. So how could he top that? By bringing in the big guns. Watch the “Switch”/theme song mash-up, the guys dancing to “Jump On It,” and Heather Graham really getting into the performance when you keep reading.
