She wrote on her personal website: 'This is crazy! I am NOT pregnant! Magazines can be so tricky with their wording! The inside states that one day I want a baby! But I'm not pregnant!
'I can foresee lots of crazy, made up stories coming out in the near future and I certainly don't have time to shut down every rumour. But believe that if you hear it from me, it will be true. Otherwise, don't always believe what you read, dolls.'
