Tiger King star Joe Exotic has revealed that he is battling prostate cancer.

The 58-year-old is in the first few years of a 22-year jail sentence for charges including animal cruelty and a plot to kill rival Carole Baskin, although he continues to protest his innocence while alleging corruption in the Department of Justice.

In a series of tweets late on Friday, Exotic claimed that he has tested "very high for prostate cancer" and will now undergo further examination to determine how advanced it is.

"My body is tired, I have lost a tremendous amount of weight, the mouth sores are out of control, I throw up more than I eat," he wrote.

"I don't want anyone's pity, what I need is when John Phillips (lawyer) gets the evidence he is working on, I need the world to help him get President Biden, VP Harris and the Attorney General to listen to the evidence and see that it's not just city cops out of control with corruption, but his very own Department of Justice and make this right and sign that pardon that Trump left behind so I can go home and get proper medical care and proper food.

"Thank you for all the love and support from all over the world. I love you all. Wish me luck...#JusticeForJoeExotic #TigerKing #JoeExotic"

The news comes just weeks after Exotic revealed that he is seeking a divorce from his 25-year-old husband Dillon Passage.
