The glamour model fears the cage fighter will use her “most intimate photos ever” to get revenge after she dumped him on UK TV after leaving reality show ‘I’m A Celebrity… Get Me Out OF Here!’.

A source said: “If sleazy photos of Katie came out it would destroy everything she’s trying to do.

“She has just come out of the jungle aiming to reinvent herself as a serious businesswoman and model parent.”

Katie’s mother Amy reportedly called Alex’s family to arrange to collect the pictures but her driver was refused entry.

However, the brunette beauty – who raises three children with ex-husband Peter Andre – allegedly has a set of graphic pictures of Alex.

The source added to Britain’s Daily Star newspaper: “Katie took these pictures of Alex for a reason and thinks they are her insurance policy. But he really doesn’t care.

“He’s got a lot of dirt on her and she must be terrified about it coming out and showing what she’s really like.”

Katie – also known as Jordan – became the unwitting star of a sex tape when home video footage of her romping with then-boyfriend Dane Bowers was leaked on to the internet and eventually released as a DVD in 2003.
