The star is one of the show's biggest signings ever, and is apparently slated to appear in the 2019 season of the survival series, which sees contestants living together within an Australian jungle camp, coping with few creature comforts.
A source told Britain's The Sun newspaper the 70-year-old will be flying to the show's location in Australia next week, November 4, adding, "She's such a huge name and a great get for producers."
"(The network) ITV thinks she is one of their best-ever signings. It's a real bolt from the blue. They've asked her every year for a long time, but she finally felt the time was right."
"I'm a Celebrity... Get Me Out of Here!" kicks off on November 17.
