And producers are said to be keen for Farrah - who ventured into porn after her TV career stalled - to "sex up" the house.

A source shared: "Bosses want the show to be more X-rated. She'll add real sex appeal."

Meanwhile, former 'The Apprentice' candidate James Hill - who was previously convicted for assault and claimed to have romanced fellow candidate Lauren Riley - is also set to appear on the reality show.

An insider told The Sun newspaper: "James might not have won 'The Apprentice' but he was the biggest character.

"He is cocky, mouthy, won't ever take no for an answer and he has an eye for the ladies."

If James and Farrah do agree to their deals, they will be joining 'The Only Way Is Essex' star Gemma Collins, who lasted just three days when she took part in 'I'm A Celebrity...Get Me Out Of Here!' last year.

A source said previously: "This is Gemma's chance to put the dramas of 'I'm A Celebrity' behind her and show people what she's really capable of.

"Going into the jungle, Gemma wasn't in the right state of mind. She had so much going on in her life and it all just got too much for her."
