Cat Deeley has revealed that she is "over the moon" to be expecting her second baby.

The 41-year-old So You Think You Can Dance? presenter, who had her first child Milo in January 2016 with husband Patrick Kielty, is expecting a new baby in the spring.

She told her fans on Twitter: "Over-the-moon to share that Milo is going to be a big brother! Can't wait to be a family of four in the spring. We're all so excited."

Last year, Deeley told how she wanted more children with 46-year-old Irish comic Kielty and that the pressure was on because of her age.

"I would love some more. But I have got to get on with it if I do," she told the Daily Mirror.

"When you go for your check-ups they call you a 'geriatric mum'. That is the terminology they use, I swear.

"They say, 'Ma'am, you are triple high risk'."

Former CD:UK host Deeley and Kielty married in a secret ceremony in Rome in 2012, having been long-time friends.
