Even though he's a big-time movie star, sometimes you can't really escape your roots. And to many fans, that's completely fine!
According to The New York Post, when Will Smith appeared on BBC in the U.K. to promote his new movie, Men in Black 3, little did he know host Graham Norton was going to pull out a hidden keyboard for another guest to start playing the theme song to The Fresh Prince of Bel-Air!
You can guess what happened next: Within moments, Will started crooning the lyrics and the audience chimed in and bopped along, too!
Be sure to catch the clip below. We must admit after all these years, it's definitely a catchy tune. Don't you agree?
