‘Excruciating’: Yep, so Will Smith’s marriage sounds like great craic

He's been married to Jada Pinkett Smith for twenty years, and Will Smith has finally revealed the secret to a happy relationship.

Unfortunately, it's a little less romantic than you might think. Speaking at the LA premiere of his film Concussion this week, the actor said the main thing keeping his marriage going strong was his and Jada's insistence on "not quitting."

And indeed, the 47-year-old star admits his two decades of marriage haven't always been easy.

"It’s like our marriage was the most difficult, gruelling, excruciating thing that we have ever taken on in our lives. And you know we're just not quitters."

While many long-term couples would say teamwork is important in a relationship, Will seems inclined to disagree.

"I would say is that we never went into working on our relationship.

"We only ever worked on ourselves individually, and then presented ourselves to one another better than we were previously."

Over the last few years the couple, who have 17-year-old son Jaden and 15-year-old daughter Willow together, have been plagued by divorce rumours.

However they've always insisted they're as strong as ever – with Will even taking to Facebook earlier this year to put an end to the speculation.

"So, in the interest of redundant, repetitious, over & over-again-ness… Jada and I are…NOT GETTING A DIVORCE!!!!!!!!!!!!!" he wrote.

"I promise you all – if I ever decide to divorce my Queen – I SWEAR I'll tell you myself."

Their approach to marriage might be a little unorthodox, but twenty years on it still seems to be working for this pair.
