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."
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."
