She's Kerry Katona's second eldest child - a daughter she had while married to Brian McFadden.

And now Lilly-Sue is seriously grown-up looking... despite still only being 15. The teenager posed up alongside her famous mum in a snap that Kerry posted on Saturday: the former Atomic Kitten singer used the caption: "Playing dress up with my @lils.mc omg she’s getting so grown up!!!!!" Plenty of fans afterwards agreed that Lilly-Sue was a little beaut - and so like her mum. "Wow kerry lily looks so grown and very much ur double," said one, with another stating: "She is your twin!" Last September, it was revealed that Kerry's eldest daughter Molly - who is a year older than Lilly-Sue  - was moving to Ireland to live with her paternal grandparents. Brian McFadden said the teenager wanted to focus on her studies. "I think it'll be easier for Molly to concentrate on her exams there. It's going to make things harder now for us all to be together, but you have to make sacrifices," he told OK magazine at the time. Last year, Brian furthermore said that following years of turmoil he and Kerry have a really good relationship now. "We don’t speak about everyday stuff but we do work closely with anything to do with our kids," he told The Sun. He added: "Our relationship is the best it has ever been. There are no fights or arguments, its all good now. It’s taken a long time to get there but I’m glad it’s like that." Atomic Kitten star Kerry, 36, also has children Heidi, 10, and Max, eight - from her marriage to Max Croft. She and her third husband, George Kay, furthermore have a daughter Dylan-Jorge, two. Kerry and Brian married in 2002 in Dublin and separated two-and-half years later.
