Irish singer-songwriter Una Foden has welcomed her second child, a baby boy, with husband, rugby star Ben Foden.

The 29-year-old England and Northampton Saints star took to Twitter to announce the news.

The 33-year-old Saturdays singer, also took to the micro-blogging website to gush about her new born baby boy.

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!"

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.
