For the event on the Warner Bros. lot in Burbank, California, Will wore a navy blue suit, while 23-year-old Trey -- Will's son from his first marriage to Sheree Zampino -- rocked a black one with a burgundy button-down.
The rest of the crew opted for more daring ensembles, which is not unusual for these artistic actor-singers. Budding fashion icon Jaden sported a white jacket covered in green leaves, a black T-shirt reading JUST Water (the business venture and environmental initiative he's a part of, which supports packaging spring water in renewable materials to lower its carbon footprint), and gray jeans. He was even carrying a bottle of his water on the carpet, though the smiling seemed to be left to his proud father.
Jada, 45, went pure fashionista, rocking a sharp white pantsuit that featured a long jacket with a blush camisole underneath. She accessorized with a gold watch, earrings, and glittery sandals, and wore her hair pin-straight.
As for Willow, she sported the most casual yet very age-appropriate look: a long blue patterned blouse with a leather jacket, matching black tights, and Puma sneakers. The 15-year-old also shared a very sweet moment with her dad, who held on tight to his little girl with a hug.
The Smiths have always been supportive of one another. In fact, Jaden walked the red carpet with Will at the New York premiere of Suicide Squad in August, where the 48-year-old actor told ET, "They saw it three days ago, and they're coming to see it again. They told me I don't ever have to work again. They said this is it. I'll never make anything better than this. Deadshot is the best character I will ever play, and I need to stop making movies. That's the family consensus."
