Nicole: (revealing her and Keith Urban have vowed never to be apart for longer than a week) We have a thing where we're not separated for more than seven days. It's not a negotiation. It is such a desire to be together. It's a lovely place to be in a relationship where you just desperately want to be together. We'll do whatever it takes. Keith flew to Australia once for six hours so as not to break the rule, and I said, 'Oh, you don't have to.' He said, 'It's not have to, it's I want to.' That was big - I heard that loud and clear, 'There's no have-to, Nicole.' Which is a lovely thing.
