This never gets old. Will Smith a.k.a. The Fresh Prince was at The Palms in Las Vegas, yesterday (August 15) in support of his son Trey's DJ gig with former partner DJ Jazzy Jeff when he decided to steal the show. Apparently feeling the vibes, the rapper turned mega star actor rocked out with the crowd to "Jump On It" before blessing attendees with a full rendition of the timeless 1991 classic, "Summertime."

Check out the footage, above.
