The pregnant 35-year-old singer revealed that she and husband Stephen Belafonte are considering leaving Los Angeles to move back to England, and let it slip that it could have something to do with the talent show.
Talking to Heart radio, 'The whole family is going to move, I think. I've yet to have the conversation with my husband but I have been thinking about it. I think if I'm going to move here, I'd move here for quite some time so the kids can get settled in school.
'I don't think I was meant to say that though. Oh sorry, pregnant brain, maybe that was a secret.'
Asked if she was set to replace Cheryl Cole on the programme, she replied, 'Maybe so... anyway... I'm in so much trouble, why did I do this interview? I don't talk about anything unless it's ready to go.'
