Katie Price‘s mother has reportedly made Alex Reid sign a contract, agreeing not to mention her daughter in the Celebrity Big Brother house.

An insider told Heat: “Amy, Katie’s mum, made Alex sign a disclaimer to say he won’t talk about Jordan – apart from generally – at all.

“It also said he can’t mention the kids or Pete – and if he does he’ll be in serious trouble.”

They added: “[Katie] hates not being the one in control. She’s already dumped him once after her stint in the jungle last year, and it could happen again if he does or says something seriously embarrassing.

“They both know it – which is why Alex is on his best behaviour. He’s even told Jordan that he will spend all his earnings from the show on her, to prove to her that he’s not in it for the money or fame.”
