Nicola McLean is pregnant with her third child.

In an interview with Britain's OK! magazine, she revealed: ''I'm so shocked but very pleased. To be honest, because of how ill I've been with my eating disorder, my periods had stopped and I thought I'd blown any chance of having any more kids so I was pretty devastated, because I want a house full. But suddenly my periods started coming back, which meant I was getting better.

''But the baby definitely wasn't planned, I have the coil! I know that no contraception is 100 per cent, you just Hope it is, or hope it doesn't in my case - I feel very lucky.''

Nicola says she would the baby to be a girl although would be happy if she had another boy.

The British beauty said: ''I'd love a girl but I'd also be happy with a boy because I love going to the football, but I would love all the ballet and tutus too! I love children, I love being a mum and having a big family.''
