Watch Will Smith Perform ‘Summertime’ in Front of Vegas Crowd [VIDEO]

Even though he's one of Hollywood's biggest actors, Will Smith proved to a Las Vegas crowd on Friday that hasn't forgotten his musical roots!

TMZ reports that Will Smith's 21-year-old son, Trey, was co-DJ'ing at Las Vegas' Palms Resort with DJ Jazzy Jeff when his superstar dad got on stage and joined them in performing his 1991 hit 'Summertime.' 'Summertime' was the lead single off of 'Homebase,' the fourth album Will Smith and DJ Jazzy Jeff collaborated on as DJ Jazzy Jeff & The Fresh Prince.

Will paid tribute to his former music partner as he took the mic on stage in front of the excited crowd. "Give it up for Jeff, give it up!" he shouted, before adding, "It's been a minute. Jeff, when was the last time I saw you? We haven't been on stage [together] forever!"

He then got the crowd going as the two Smiths and Jazzy Jeff broke into the song, 'Summertime,' with Jeff on the decks and Will on vocals. And even though the song is almost 23 years old, Will Smith proved that at the age of 45, he still has what it takes to rock a crowd.
