Xtra Factor presenter Holly Willoughby has revealed she is pregnant with her first child after Simon Cowell accidentally leaked the news.

The 27-year-old was forced to reveal her pregnancy live on air on Saturday night after Cowell and fellow X Factor judge Louis Walsh referred to her being with child.

"Congratulations to you," said Cowell while being interviewed on the ITV2 show before Walsh added: "On the pregnancy".

Willoughby replied: "Yes, I am pregnant - I don't know if people know that yet.

"I'm feeling emotional tonight, let's move on," she added.

However, the Dancing on Ice host also referred to her pregnancy later in the show when Will Young - who had performed on The X Factor - offered her a drink.

"I can't have a beer, I'm pregnant," she responded.

The former children's TV presenter, who also hosts Streetmate and Holly and Fearne Go Dating, has been married to TV producer Dan Baldwin for just over a year.
