Ben Stiller: 'Humour is the key to happy marriage'

Actor Ben Stiller credits a good sense of humour for his happy marriage.

The funnyman wed actress Christine Taylor over 15 years ago, and the couple is still going strong.

Looking happier than ever at the New York premiere of Ben's new movie Zoolander 2 on Tuesday, (09Feb16), they were happy to chat to the media about what keeps the romance alive.

"I think you got to laugh," the actor told Entertainment Tonight when asked for the key to a happy Hollywood marriage, "because, you know, after a while life is life, you know? We all have to deal with what life throws at us, so you got to have a sense of humour about it. If you can share that, at the end, it makes a huge difference."

Ben and Christine, 44, married in May, 2000 after meeting on the set of TV show Heat Vision and Jack, and Ben previously opened up to Parade magazine about the moment he realised the actress was the woman he wanted to spend the rest of his life with.

"(Our) relationship was a gradual thing that happened over a quick period of time, maybe seven or eight months," he said.

"We just started hanging out with each other and it developed into, 'Wow, this feels great. I really like this person. I think I love this person. I really do - I love this person.' It hit me out of the blue."

The couple, who star in the Zoolander sequel, brought their two children, 13-year-old daughter Ella and 10-year-old son Quinlin, to the premiere - and the little boy stole the show from his parents.

As the family gathered together for the awaiting photographers on the red carpet, Quinlin did his best 'Blue Steel' stare, becoming the perfect mini-me to Ben's Zoolander model character.
