Una Healy from The Saturdays has announced that she is expecting her first child with the English rugby player, Ben Foden.

The Irish member of the girl group told The Mirror that she is delighted:

"I'm really happy! It was totally unexpected, but me and Ben are really excited."

Her bandmates have said that they can not wait for the arrival of the sixth member of The Saturdays, who is expected to arrive in early 2012.

The Saturdays are currently enjoying the success of their latest single, 'All Fired Up', which is sitting at the number 3 position in the UK charts. 

The stars will be starting their first arena tour on December 2 in Bournemouth and finishing on December 19 in Dublin.
