Kerry Katona, 34, wrote proudly: "Love how you have all our babies names tattooed on your arm!
"You really are the most amazing dad!! @mrgsjkay love you so much xxxxx"
She also retweeted a fan's praise for George, which read: "It's a real man that invests his whole heart in children they didn't create.
"We're lucky women to have men like ours @KerryKatona7 xxxx"
George responded to the praise on Twitter, dismissing it and insisting it wouldn't have been possible for him to have biological daughter Dylan-Jorge Rose's name tattooed onto his arm and not include Kerry's other children.
He wrote simply: "Standard babe, can't have one without the other."
Although he did cheekily add: "Running out of places to put them if we have anymore ;-) xxx"
It's unsurprising to see George so dedicated to Kerry's children; while George Kay is DJ Rose's biological father, his Twitter profile proudly proclaims that his a father to five amazing kids - showing just how happy he is to be a stepdad to Kerry's other children, Molly and Lilly (Brian McFadden's daughters), and Heidi and Max (Mark Croft's daughters).
And, over Father's Day weekend earlier this year, George retweeted an image of an adult bumping fists with a small child, emblazoned with the slogan: "Having kids doesn't make you a father. Raising them does."

He also uploaded an image of a Father's Day card which Kerry and Brian's daughter Lilly had written for him, captioning the card: "This was what Lilly wrote in her card for me.. it made me well up! Love her to bits!! What an amazing Father's Day xx".

Lilly, aged 11, wrote in her card: "A daddy is a man who cares for his child's physical and emotional needs. he puts their wants and needs in front of his own and that is why I am proud to call you my Dad."
She signed it: "Lots of love from your little girl, Lilly"
It's lovely to see that Kerry has found a man so dedicated to making a life with her and her children, isn't it?
