Kimberley Walsh wants to have "one more" baby.
The former Girls Aloud singer has two sons - three-year-old Bobby and 19-month-old Cole - with her husband Justin Scott, and has said there may be a third child on the horizon in the future, as she's keen to keep expanding their brood.
She said: "I think I've got one more in me. I'm one of four so I think that's why I'm like: 'We can just keep going!' I didn't find pregnancy difficult, and I think if you've had a good experience then that makes the decision a bit easier."
But Justin - who was formerly a member of boy band Triple 8 - might take more convincing, as both their sons are "so full-on at the moment" that he can't see them adding a third baby to their already hectic household.
Kimberley added: "I think once this phase passes, Justin will be like: 'Ah OK then'. It might feel more doable to him. It's just that they're so full-on at the moment.
"It almost feels like they're taunting me and running in opposite directions. By the time I've got them to bed I don't even known what I look like any more. They are absolute nutters, my two. I thought they'd be quite placid like me, but they've both turned out full of character and quite cheeky."
Meanwhile, the 36-year-old singer made friends with Giovanna Fletcher - who has two sons, four-year-old Buzz and two-year-old Buddy, with her husband and McFly musician Tom Fletcher - through their young children, and admitted a recent playdate with their broods didn't go according to plan.
Speaking to Fabulous magazine, the 'Love Machine' hitmaker said: "I didn't know her that well, but we have two boys each and they are similar ages, so she was like: 'Come over! It'll be great!'
"Previous to this Bobby had been an angel child, but he was so naughty, challenging everything I said, and I just didn't know how to parent in that situation. Giovanna was all: 'Ah it's fine, we've all been there.' Urgh. She sort of invited me back, but it hasn't happened yet."
