Saturdays star Mollie was snapped cuddling two-year-old Aoife at ITV studios in London following appearances on This Morning and Loose Women.
Alongside the picture, which Mollie posted on Instagram, she commented: "Practising being "mummy"! Doing a good job, right!?"
Mollie is currently in a relationship with US music producer Jordan Omley and, given that Una, Rochelle Humes and Frankie Sandford are already mums, she is often asked about babies.
But in an interview with Cosmopolitan in January, Mollie admitted that she isn't broody just yet, despite adoring her bandmates' children and her own nieces and nephews.
Mollie told the magazine: "It totally changes your life and I have the best of both worlds – I can play auntie but not have to do all the nappy changing! One day I'd like to have loads of kids, but I'm not quite ready for it yet."
Meanwhile, Aoife wasn't the only mini Saturday at ITV today, as Frankie also brought her son Parker along.
Frankie Instagrammed a gorgeous picture of Aoife planting a kiss on Parker as she and Una waited backstage with their children.
Writing next to the snap, she said: "Lots of love and kisses from Aoife today. Bring your kid to work day! @unathesats."
