She said it's hard to know when you'll go into labour so she would keep working right up until the end.

According to the Mirror, she added: "My job is sat on a sofa. I'm sitting down all the time on This Morning, and on Celebrity Juice I'm behind a desk. So don't feel too sorry for me."

And now she can enjoy baby Chester on the sofa at home for a while. Huge congrats to the new parents.
