While former Fresh Prince star DJ Jazzy Jeff was spinning hits at the hotel's Ditch Fridays pool party Aug. 15, the hip hopper played "Summertime," and Will Smith popped up on stage (!) to rap along to it.
After he finished performing the duo's classic song, Will really got into it. According to E! Online, the After Earth star ripped off his shirt when "Jump On It" started playing later on in the day, and the majority of the crowd started jumping up with him.
Will wasn't only there to hype up the crowd with Jazzy Jeff, though. He also was on hand to support his oldest son Trey Smith, who was spinning during a special guest set as DJ AcE.
"In Vegas at a pool party with Jazzy. This dude is RIDICULOUS on the tables!!!!! STILL," Will captioned a Facebook shot of himself posing with Jazzy Jeff with a bunch of partiers throwing up their hands in the background.
Just to give fans more of an idea what it was like to be there, the movie star also posted a video showing screaming fans going wild in the crowd. "This is the best pool party ever," Will said in the clip.
