The 26-year-old could earn a cool £250,000 if she agrees – despite turning the show down in the past.
A source told the Daily Star: "They have dug deep in the past for stars like Katie Price and they know bringing Tulisa on board will guarantee some wild antics in the house.
"She's opinionated and feisty and they're willing to negotiate with her as much as it takes to get her to sign on the dotted line."
According to the insider, Tulisa is considering the offer and producers are willing to do whatever they can to make the show work with her schedule.
"Tulisa isn't on X Factor any more and her work schedule has changed a lot in the last year.
"[She] is likely thinking this over very carefully. She's seen the show and knows what she's in for."
Last year Tulisa denied rumours she was going on I'm a Celebrity… Get Me Out of Here, insisting at the time that she's not a reality star.
She told Nick Grimshaw: "I'm a musician. I've never been a reality TV star and it's not the way I want to go."
