The 39-year-old actress, who has two marriages under her belt, said that if she was '100 per cent sure' then she would do it all again.
She told People: 'I would consider getting married again because I want kids. That's why I would do it. I believe in marriage as a whole because my parents were married for 43 years, so I have the best example in the world of what marriage can be. You just have to be 100 per cent sure. You have to go in with your eyes wide open and realise that it's probably going to take a lot of work and maybe some couples therapy perhaps.'
She added: 'When the going gets tough, you don't get going - you hang in. So marriage to me is such a gigantic commitment that it's not something I'd ever go into lightly any more. I've learned my lesson.'
