We reported not too long ago that Will Smith and his former music duo, Jazzy Jeff, performed at a U.K. music festival. We now learn that last night the 49-year-old was back again to sing some of his most popular tracks with his son, Jaden, by his side. 

Will and Jaden, as well as Will's other son Trey, all attended Paris Fashion Week last night for the opening of Louis Vuitton's boutique at Place Vendôme. Just a few hours after the event began, with Jaden warming up the crowd with a solo performance (dressed head to toe in L.V.), no one would have expected that Will would yet again join forces with Jazzy Jeff for the fashion celebration singing big hits like “Gettin’ Jiggy Wit It,” “Summertime” and “Miami.” 

The crowd was obviously going wild, where Will was responsive and playful seen grabbing phones from the crowd and taking selfies with those in attendance.“She just looked at me like, ‘You better take a picture with me,’” he joked. He then performed the hit "Just The Two Of Us" which is famously based on his older son, Trey.

“I wrote this right after we got home — for the first time in my life I had a baby, and it was crazy,” he said.

We shared a video in the summer of Jazzy Jeff and Will in the studio where they followed up with two European show dates. Jazzy Jeff is currently on tour, we'll just have to see if Will will make any other appearances along the way.

One of Will's most popular movies, Men In Black, is about to have an official spinoff in the upcoming years. We reported last week that the Steven Spielberg executively produced film will follow new characters that are based on the iconic Agents K and J - played by Tommy Lee Jones and Will.
