The Sun reports that her exclusive contract with Channel 4 means she can't take part in other shows, despite ITV placing her on their wishlist of stars for the new line up of celebrity campers.
The tabloid claims that Scarlett has also had to turn down the opportunity to become a regular on Rylan Clark's new Channel 5 chat show Up Late With Rylan, which begins next month.
“Scarlett is one of the most sought-after names in TV right now. Producers and casting directors have cottoned on to how popular she is," a source said today.
They revealed: “ITV have made an approach for her to go on I’m A Celeb but she isn’t allowed. It would break her exclusivity contract with C4."
A spokesperson for Channel 4 said in response to the reports: “Scarlett is not taking part in I’m a Celebrity and will continue to entertain Gogglebox fans from her sofa.”
They added: “Scarlett was approached by [Up Late With Rylan]’s producers but turned down the offer as it conflicts with her exclusive C4 Gogglebox contract.”
It's claimed that Scarlett would only be free to join other shows if she quit her role on Gogglebox.
George Gilbey did just that in 2014 to sign up for Celebrity Big Brother, although his family proved so popular that he ended up being invited back.
I'm A Celebrity 2016 will air on ITV later this year.
