Una and Ben, who got married in June 2012, already have a two-year-old daughter Aoife Belle, born in March 2012.

Last year in September, the Voice Of Ireland judge announced the baby news on her social media accounts, by sharing a picture of her little girl wearing a t-shirt saying: "I'm going to be a big sister!"

I know lots of people have been guessing and Ben and I can now confirm that Aoife is going to have a baby brother or sister next year!!! We're all very happy

During an interview with Hello! Magazine, Una talked about her second pregnancy.

"Ben was adamant from the moment we knew we'd conceived again that we were having a boy," she said.

"I was convinced I was carrying a girl, mainly because this pregnancy is so similar to last time.

"I was actually a little bit taken aback when we found out were going to have a son. But now I'm over the moon and can't wait to meet our little boy," Una added.
