Caitlyn Jenner Shows Off Her Bikini Body While Filming 'I'm A Celebrity ... Get Me Outta Here!' In Australia

Caitlyn Jenner showed off her bikini body in a black two piece swimsuit while filming I'm A Celebrity ... Get Me Outta Here! on Monday, November 18. Kris Jenner's ex went without makeup as she showered off in the Australian jungle. The I Am Cait star's decision to go on the reality show took her famous family by surprise, but they are reportedly supportive of her choice to participate.

Caitlyn, 70, previously revealed that her family initially asked her why she wanted to go on the U.K. show. "I said, you know what, I need a break, I like challenges. I did the U.S. version of this and it was a very interesting experience last time I did it. Being in the jungle is certainly not easy and yes, it is totally back to basic, but I thought this would be a great opportunity to leave everything behind for three weeks. Last time, it was almost like a cleansing of the soul!” she said in an interview.

Kendall and Kylie Jenner's father allegedly promised to not talk badly about the Kardashians while filming.

"Caitlyn is in a really great place with the rest of the Kardashians especially after hanging out with most of them for her birthday. The family was made aware that she was going to do the show and Caitlyn promised she wasn’t going to drag the family down in any way while she is a part of the show. The girls and Kris are very supportive of Caitlyn to do the show, she is getting paid amazingly well and people are going to see the real person that Caitlyn is and they fully support all of that," a source dished to HollywoodLife.

Caitlyn has proved time and again that she has a pretty thick skin when it comes to discussing her transition. She even poked fun at herself during an appearance on Comedy Central's The Roast Of Alec Baldwin in September.
