'Xtra Factor' presenter Holly Willoughby has said that she worries about her baby son Harry throwing up on 'The X Factor' judges.

The television presenter told Now: "I'd go to the judging room and Dannii and Cheryl would be like, 'Hurry up and bring him in'."

"I was always scared to let them hold him after he'd just eaten though, in case he puked all over their lovely outfits."

"They would be holding him and I'd be thinking, 'Harry, please don't chuck up'. They were so good with him."

Joking about her son, Willoughby said: "Harry is the only person who's not scared of Simon Cowell."
