Will Smith brought his entire family along to support his son Trey Smith, an up-and- coming DJ. The actor, along with wife Jada Pinkett Smith and kids Jaden and Willow, packed into the DJ booth at Jelsomino in Miami Beach to hear Trey’s techno set. Jada left at 2 a.m. with younger kids Willow and Jaden, while Will stayed on with Trey until nearly 4 a.m. The actor also grabbed the mike and treated the crowd to a rendition of his song “Welcome to Miami.”
