I'd be happy to stay single now because I've always been in relationships. For the first time ever I can do what I want, when I want, with who I want, without answering to anyone.

I've never once heard my mum shout and she's 83 now. She's incredible. She's very, very happy, slightly eccentric but loves laughing, which I do too.

I was away a lot on 'Countdown' when the children were young and I couldn't have done it without Mum's help. Because she was at home running all of that, I never had to worry about them.

I write about the men you want to read about but don't necessarily want to be married to.

Well, I actually wrote her a letter a couple of days ago congratulating her. The tone I tried to convey in the letter is, look, you are a part of a great American historical process.

I studied international relations and economics at the University of Virginia. I paid my way by working as a bartender in the summer and at three part-time jobs during the year.
