The Saturdays star Una Healy has confirmed that she and boyfriend Ben Foden are expecting a baby.

The singer said she is "excited" about being a mum, and that the couple are "over the moon" about the pregnancy.

Una has been dating rugby player Ben since 2008.

She told The Sun that the pregnancy was "unexpected".

Healy's bandmates Frankie, Mollie, Vanessa and Rochelle, are "excited to have a sixth Saturday. They'll be aunties," she said.

According to The Mirror, Una doesn't yet know if she's having a boy or girl.

A friend of Una's told The MIrror: "All the girls are absolutely overjoyed for Una – they can’t wait to meet the first Saturday baby!"

They added: “He or she is going to have four very excited aunties when they arrive in late March. All of Una’s family are really supportive, too. She was overwhelmed by the response when she went home."

Una said she will continue to work with The Saturdays right up until she's "fit to burst".
