Collateral Beauty premiere: Will Smith reveals he cried ‘like crazy’ when daughter Willow turned 16

Will Smith has revealed that he cried ‘like crazy’ when his daughter Willow turned 16.

The Hollywood A-lister admitted to getting very tearful over his children as he walked the red carpet at the London premiere of Collateral Beauty on Thursday night.

“I cry a lot. My daughter just turned 16 and I watched her drive away from our house about three weeks ago,” he said.

“I was out there in the driveway as she was driving away, just boo-hooing like crazy, thinking: 'My baby is 16 years old.'

"That was my highlight of the year too, it felt like a huge parenting accomplishment.”

He added: “But she doesn't really pay enough attention, she feels safe in the world so when she's driving she's very happy, I want her to feel less safe when she's driving."

The Oscar-nominee plays an advertising executive who tries to cope with the death of his daughter in the new film.

Speaking about the harrowing subject matter, he said: “It feel like we created something special, if it hits a person at the right time it can be helpful in someone's life.

"It was a beautiful opportunity to get perspective and get clear on the things that are really important, and how much crap we do that just really doesn't matter it's painful but great to be cleansed of some of those material world addictions."

Smith was joined on the red carpet at the Leicester Square premiere by co-stars Helen Mirren and Naomie Harris and Ed Norton.

Collateral Beauty is in UK cinemas on December 26.
