Una Healy is expecting a baby.

The Girls Aloud singer and her England rugby player boyfriend Ben Foden - who have been dating for three years - are expecting their first child together in March, and they are "really excited" about their forthcoming arrival.

The Saturdays singer explained: "I'm really happy! It was totally unexpected, but me and Ben are really excited."

Her bandmates Mollie King, Frankie Sandford, Vanessa White and Rochelle Wiseman also revealed they are thrilled for the 29-year-old stunner.

They said in a statement: "We're so excited for Una! We can't wait to have a sixth Saturday. Ben and Una are going to be fab parents."

The 26-year-old sportsman - who is currently representing England at the 2011 Rugby World Cup in New Zealand - is said to be "delighted" with the news.

A source told the Daily Mirror newspaper: "Ben's delighted. He's looking forward to celebrating fully with Una when the Rugby World Cup is over."
