The former air hostess suffered a miscarriage just a few months into her relationship with the former Cheers actor, but the pair tied the knot in February and is eager to try again.
Having watched her 56-year-old husband with his children Mason and Jude, from his previous marriage to Camille Grammer, she is certain that he will be a great dad to their kids.
'He's such a good father. I've never known a man like him,' the 29-year-old told Us Weekly whilst appearing at the Tony Awards. 'He's just so full of love and he's wonderful. You couldn't ask for more.'
Camille and Kelsey are currently engaged in a bitter custody battle for their kids, and he took a swipe at his ex, who at the time of their separation was starring in The Real Housewives Of Beverly Hills.
'I made a conscious decision that I wouldn't be at least playing on my personal life in front of the cameras - that's just disrespectful, I think, for the whole situation, [and] for Kayte as well,' he told reporters. 'It's very hard at this point. But I'm not going to say much about that. I'm going to do my best to make sure my kids are always OK.'
