The former Atomic Kitten member is so insecure about her relationship that she has even asked the detectives to compile a dossier on what the other ladies are wearing and if they have a boyfriend or not. "She's terrified Mark will get back with one of them," News of the World quoted a source close to Katona as saying.
"Kerry thinks that if they have a regular boyfriend, Mark won't be able to get back with them," the source said. "She wants to know what Louise wears, her hairstyle, even how slim she is. She's desperately insecure," the source added.
The detectives have been watching the two women, who both live in Warrington, Cheshire, for several weeks now.
