Robbie Williams: `We are built to f***`

The 37-year-old Take That singer married American actress Ayda Field last year and said that so many people are unfaithful nowadays that maybe the whole system of monogamy needs rethinking.

He told Esquire magazine, 'The rules aren't set up right, because people are f***ing outside of their marriages, outside of their relationships.

'People get caught out every single week in the newspapers. What does that mean?

'I think that means we're built to f***. And marriage, that whole institution, is made-up bull.

'I am pleased there is a media waiting for me to f*** up because it keeps me on the straight and narrow. But if it wasn't for jealousy and social constraints, I think the rules would be different.'

But he added that even if he could get away with having a bit on the side, he couldn't do it to his wife.

Asked if he would cheat, he replied, 'Actually, no, because I don't want to break Ayda's heart. That's the last thing I want to do. I met Ayda I fell in love, that's what happened.

'But I would be way more tempted because at the end of the day I am a man, with the stuff that makes you a man - go forth and multiply. And multiply with absolutely everyone.'
