Holywood funnyman Ben Stiller claims laughter is the best way to a successful relationship.

The 44-year-old admits his relationship with wife of nine years Christine Taylor works because the pair share a sense of humour, reports celebrifi.com.

'For me, laughter is such a huge part of a relationship. My wife has a great sense of humour. What I like is to try to make her laugh,' he said.

'Sometimes she laughs at things that I take too seriously, which I find helpful in keeping me grounded. I used to be a workaholic, but now I'm happy at home. For the first time I'm beginning to feel grown up,' he added.
