The couple were out together to celebrate the 21st birthday of Will's son Trey – from the Men In Black star's marriage to Sheree Zampino.

They were joined by children Jaden, 15, and Willow, 13, and according to US Publication People, "didn't leave each other's side" as they had dinner at plush oriental eaterie Hakkasan.
At one point the pair were spotted looking affectionate as they danced together.
Most of the group – which included 55 guests of Trey – moved on to LAVO Italian restaurant and nightclub at The Palazzo to dance the night away.
Jada stayed in the restaurant with underage Willow and Jaden, but Will was spotted giving his wife a kiss before he left.
It was a night to remember for Trey – who was presented with a birthday cake by the club and invited to take over the decks while his dad cheered him on and captured the moment on his phone's camera.
The family outing marks the first time Jada and Will have been seen out socialising together for several months, amidst rumours of a marital rift.
Stories have circulated that the pair are living separate lives and that they've put their family home up for sale.
Then Will's close friendship with his Focus co-star Margot Robbie was questioned after photos which the pair took in a photo booth came to light.
Margot denied that anything untoward had gone on, however, saying on Twitter that she and 45-year-old Will had been "just goofing around".
