While chatting with Jimmy Fallon on The Tonight Show Starring Jimmy Fallon earlier this week, the actor explained how his son Jaden, 18, tricked him into flying out to London so he could legally drink on his big day. Smith, 47, explained that his son asked the whole family to fly out to meet him in London since he was working. I was like, ‘Wow, like that’s cool, he told Fallon. So we go and hang out for his birthday and I’m like, ‘Man, that’s really good. He wanted his family with him.’ The Smiths enjoyed a performance by Calvin Harris before going to dinner, which was where things got interesting.
