The glamour model - who dumped the cross dressing cage fighter a fortnight ago on live TV, after he had travelled to Australia to propose to her - has agreed to give their romance another try after he bombarded her with phone calls and text messages, but friends claim she is only with him so he doesn?t sell their intimate secrets.
Katie, 31, had made Alex, 34, sign a confidentiality agreement at the beginning of their relationship, but according to Britain`s Daily Star newspaper, he signed the document using the name of his cross dressing alter ego `Roxy`, which could make it void, leaving him free to sell his story.
A source said: "She thought she was safe making him sign the agreement, but it seems the signature was never checked.
"It was very cheeky of Alex indeed, but pretty clever. There is one thing almost as important to Katie as her kids and that`s money.
"She hates the thought of people making money out of her and was not about to hand it to Alex on a plate."
Katie`s management reportedly advised her to buy Alex`s silence, but she has instead reconciled with him, leaving him "over the moon".
It was previously claimed Katie recently went into UK reality TV show `I`m A Celebrity... Get Me Out Of Here!` in order to try and win back her ex-husband Peter Andre, whom she split with in May of this year. The couple raise three children together, Harvey, seven, Junior, four, and two-year-old Princess Tiaamii.
