Caitlyn Jenner has reportedly signed up to take part in this year's I'm A Celebrity... Get Me Out Of Here! with the reality TV star said to be flying to Australia next week.

The 70-year-old has commanded one of the biggest appearance fees in the history of the ITV series; £500,000, according to The Sun.

Producers are hopeful Jenner will speak about her marriage to Kris Jenner and relationship with Kim Kardashian and the rest of her family.

"She's such a huge name and a great get for producers," The Sun quote a source as saying.

"ITV think 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."

ITV commented, "Any names are speculation until we officially announce our line up."

A start date for I'm A Celebrity... Get Me Out of Here! is yet to be announced, though it usually airs in mid-late November.
