'The moment he had a daughter, he had this amazing new appreciation for the other 50 per cent of the population,' she said.
'He doesn't skirt his responsibilities as a father. He never takes off and goes out with the boys instead of being a dad.
'He always makes the right choice - which I've never bullied him to do! He's just a good man. And it's sexy.'
