E! reports that it was the first time the friends hung out with each other musically in at least seven months, so the impromptu team up surprised hundred of fans. And TMZ was kind enough to video so those not in Vegas have some serious nostalgia feels.
In the meantime, the long time friends hugged, laughed, took some pictures, and danced around. The stars of The Fresh Prince of Bel-Air enjoyed the afternoon, but Jazzy wasn't the only DJ that Smith was partying with.
Son Trey Smith, a.k.a. DJ AcE, spun in the booth on a special guest set.
A source told Wonder Wall, "He watched Ace for a while without anyone knowing he was even there." Turns out it wasn't until Jazzy Jeff hit the stage that he came on stage. Support for his kid before celebrity; pretty awesome dad stuff right there. It's not easy to hide in a sunny, bright area and a crowd of people, either.
Smith and ex-wife, Sheree Fletcher, watched their son from the VIP booth. Fletcher's recently been seen on Vh1's reality hit series Hollywood Exes, alongside Nicole Murphy, Mayte Garcia, Jessica Canseco, Andrea Kelly, Shamicka Lawrence, and Shanna Moakler.
The pool party clearly had fun, soaking in the sun, and reveling in the unexpected guest star. So when the Men in Black star pulled off his shirt to sing "Jump On It," the crowd went wild. At 45, the man displayed a sleek stomach, defined muscles and a ton of stamina.
And ever the performer, the four-time Grammy winner even rapped the theme song to The Fresh Prince of Bel-Air.
The Wonder Wall source talked about how much the two seemed to be enjoying each other on stage. "He was singing and going crazy. He was dancing hard. As soon as he saw (DJ Jazzy Jeff) they did this crazy dance and they started taking selfies."
After the party ended, Will hung around to thank the crowd for supporting his friend and son as well as creating a fun afternoon. Ever the age of technology, he snapped a selfie and video to post to Facebook before leaving.
Though, an attempt to jump into the thwarted by personal security. Safety's important, too, Mr. Bad Boys For Life.
Later in the evening the family went out to eat at N9NE steakhouse. While there, the star signed Chef Barry Dakake's office door, which has signatures of thousands of other celebrities.
Smith's been filming movies for so long that it's hard to remember when he was "Getting Jiggy Wit It." It's a nice reminder of when MTV remembered they were a music station and rap was gaining mainstream.
And if there's any question if 22-year-old Trey was embarrassed on his dad stealing the show? His tweet celebrating the moment tells otherwise.
