The EastEnders actress, who was linked with a spot on BBC One's Strictly Come Dancing earlier this year, has been named in a rumoured lineup of 12 celebrities.
The Mirror also claims that boxer David Haye, former Doctor Who actor Colin Baker and Ladette to Lady cook Rosemary Schrager will make the trip to Australia for ITV1's jungle-themed reality show.
"Producers are delighted with this year's lineup," a production source told the paper. "They feel that there is a really good mix.
"They've been trying to find the right celebrities for a few months now and are pleased with who they have selected. Charlie is a real coup for them.
"She has been on TV since she was young and they're looking forward to the public seeing what she's really like."

Eric Bristow, former Made in Chelsea cast member Hugo Taylor, Pussycat Dolls member Ashley Roberts and former Coronation Street actress Helen Flanagan are also thought to be heading to the jungle, along with comedian Brian Conley and Birds of a Feather actress Linda Robson.
Producers are also said be negotiating with actor and WWE star Dwayne 'The Rock' Johnson, an unnamed '70s pop star and an unidentified high-profile former female MP.
I'm a Celebrity bosses were reported to be keen on signing up novelist and former MP Louise Mensch earlier this year, with an insider saying that she was "very much on our wishlist for this year".
