Holly Willoughby expecting a girl

Holly Willoughby is expecting a baby girl.

The TV presenter - who already has a 20-month-old son with her producer husband Dan Baldwin - went for her 20-week scan yesterday (04.01.11), and has revealed the couple are "excited" to be welcoming a little girl to their brood in May.

She said: "I had my 20-week scan yesterday, so Dan, myself and Harry found out what we're having.

"I didn't find out with Harry, but I found out this time and I can't keep it a secret! It's so exciting - Harry is going to have a little sister!"

However, the 29-year-old star admitted she is struggling to come up with girls' names.

Speaking on ITV1's 'This Morning' - which she co-hosts with Phillip Schofield - Holly added: "The only problem is, we had boys' names, loads of boys' names and we can't think of a girls' name. It's hard."

Holly also confessed she decided to make the announcement after she kept accidentally letting it slip that she was expecting a girl.

She joked: "When I went in to see David who does our wardrobe and he said, 'Let's see your bump after Christmas' and I said, 'There she is!' Oops!

"So it was best to tell everyone before I put my foot in it!"
