Aw, hell yes! Will Smith and son Jaden appeared on BBC One’s Graham Norton Show Friday night to promote their new M. Night Shyamalan movie After Earth. (So much for those rumors that Jaden wants to be “emancipated” from his parents.)But their appearance took a hard left turn toward the early ’90s when host Norton asked Will & Jaden to show off their rap skills. Well, Papa Smith introduced the mixmaster who’d be accompanying his rap: DJ Jazzy Jeff. And he launched into a performance of the Fresh Prince of Bel-Air theme song, complete with a second blast-from-the-past appearance. Yep, Alfonso Ribeiro, Fresh Prince’s ersthwile Carlton showed up too. Check it out!
