|Una with Aoife and Ben|
The Saturdays beauty - who has 10-month-old daughter Aoife with rugby player husband Ben Foden - may appear to be glamorous on the red carpet or in the band's music videos, but reveals she is far from it when she's at home where she changes nappies and has to clean up her daughter's vomit.
She said: "Now I'm a mum, when I'm at home I have no make up on, sick everywhere and I dress like a slob - it's just tracksuit bottoms, hoodies and I wear my hair on top of my head.
"It's totally different to when I'm at work and getting glammed up by a team of people."
Una isn't the only singer from the chart-topping girl band with questionable habits, as bandmate Rochelle Humes - who is expecting her first child with JLS singer husband Marvin Humes - recalled how she shocked her bandmates when she accepted a gym outfit from an old man to wear on a plan ride.
She explained to the new issue of We Love Pop magazine: "I forgot to pack my favourite tracksuit that I wear as soon as I get on the plane when we're flying anywhere. Luckily, this really old guy who worked on the plane said 'I've got a tracksuit I wear for the gym which you can use if you like?'
"All the girls were horrified but before he'd even finished talking I said 'YES!' It was this massive shiny gym shellsuit. I didn't even care if he'd washed it. The girls said, 'You're so shameful!'"
