Una Foden is too "exhausted" to have more children.
Una and Ben Foden
The Saturdays singer - who has three-year-old daughter Aoife and four-month-old son Tadhg with husband Ben Foden - insists they have no plans to add to their brood "at the moment" because they're both run off their feet.
She said: "I've been feeling quite tired lately because I still have to get up every night to feed Tadhg. Aoife hit the 'terrible twos' a while back. She's three now, but still cries for Mummy and Daddy. I sometimes let her come into our bed, so there's four of us in our little room! I absolutely love being a mum, but I'm exhausted!"
The flame-haired beauty added:"I don't want any more babies at the moment. I felt like I really wanted another one after having Aoife, but not this time around!"
However, Una admits having Ben - who is currently having time off from his job as a rugby player due to a knee injury - around is a great help.
She confessed in Closer magazine: "It was horrible for Ben when he found out in January that he'd be off for up to nine months, but he's very positive. And I've got lots of rugby players' wives around me - we often go for big lunches together and they come over to see the kids."
