Caitlyn Jenner could reportedly be in for a hefty fine if she criticises her family during her stint in the I'm A Celebrity jungle.
The 70 year old is said to be "banned" from discussing her famous family thanks to a Keeping Up With The Kardashians confidentiality clause.
Caitlyn allegedly signed a contract when she joined the show as Bruce – who was married to head of the family Kris Jenner – when she joined in 2007.
And, if she breaks the clause in the contract, Caitlyn could be forced to pay Kris – who is the show's executive producer – a whopping £4 million fine.
A source told The Sun: "When Caitlyn signed to I’m a Celebrity, I’m sure reality fans thought they would be getting the inside secrets of the Kardashians."

They added: "Unfortunately Kris appears to have put a stop to that right at the beginning of Caitlyn’s involvement."
The contract is said to state that those who sign it are warned they would "do the producer damage in the excess of $5m" – almost £4m – if they spill the beans about the famous family.
Caitlyn has hardly spoken about her family – including kids Kylie and Kendall Jenner – during her time on the show.

She did reveal, however, that she hasn't spoken to step-daughter Khloe Kardashian for five years after coming out as transgender.
Caitlyn told her campmates: "I don’t know, we were really close, I raised her since she was five years old, I really don’t know what her issues are."
She added: "It’s been five or six years and I really haven’t talked to her since."
Viewers were also left "heartbroken" when Caitlyn's care package from home didn't come from her children.
