47-year-old actor Will Smith opened up about his 20-year marriage to his wife, Jada Pinkett at the Nov. 23 premiere of his new movie, ‘Concussion,’ where he said despite their refusal to split, their relationship is both ‘grueling’ and ‘excruciating.’ He said this when he was interviewed by Entertainment Tonight, when they asked him how they keep their relationship so strong.

“We've been married 20 years and we've been asking ourselves [what’s the secret to marriage] and really at the end of the day it’s just not quitting,” the 47-year-old actor said of Pinkett Smith, who he first started dating in 1995 and then married two years later. “You can’t expect it to be easy, it’s like our marriage was the most difficult, grueling, excruciating thing that we have ever taken on in our lives. And you know were just not quitters.”
“If there is a secret I would say is that we never went into working in our relationship,” he continued. “We only ever worked on ourselves individually, and then presented ourselves to one another better than we were previously.”
