During her Fubar Radio show today, the pregnant model said she approved of George, who has known Kerry since they were teenagers growing up in Warrington.
Katie said: "George is actually lovely. He's absolutely massive. A gentle giant."
"I actually saw her at my baby shower on Sunday," she continued. "Kerry came with two of her girls. She seems really happy. I feel sorry for Kerry. She's a bit like me. There's this perception that you're someone you're not.
"People must think I've lost the plot or whatever, but it's the same with Kerry. When you meet her she's completely different.
"She's trying to get on with it. She admits she's bankrupt and is just trying to get along with everything. She has five kids, been married three times. We always say we're so similar. If it doesn't work with that guy we get the stick for it, but it's not always us."
Katie said she wanted to get Kerry on her Fubar Radio show so Kerry could show off the real her - not the person people may imagine her to be.
Katie added: "I think s**t happens with her like it does me and all we both want is to be loved and be happy. We have our children and don't want men to keep coming in and out of our lives."
Atomic Kitten star Kerry became engaged to George to April 2013 when he popped the question in Blackpool. They welcomed their first child together, daughter Dylan-Jorge Rose, the following year.
Kerry is also mum to daughters Molly and Lily-Sue from her marriage to Brian McFadden, and daughter Heidi and son Max from her marriage to Mark Croft.
Katie is currently pregnant with her fifth child; her second with estranged husband Kieran Hayler. Their first child, Jett, was born last summer. Katie also has sons Harvey and Junior and daughter Princess from previous relationships.
