The Olympic gold medal winner is currently starring in British jungle survival show "I'm a Celebrity... Get Me Out of Here!", and opened up about the lengths her billionaire daughter goes to in a bid to keep herself and her family, including 21-month-old daughter Stormi, safe.
According to the make-up mogul's dad, "Kylie will spend anywhere between $300,000 and $400,000 a month."
She added, "(It's) a ton of money."
As her campmates questioned what it was like to live everyday life with that kind of presence around them, the star explained, "They're used to it. They've been doing it forever. They like the security guys there."
Meanwhile, Caitlyn also revealed stepdaughter Khloe Kardashian was "p**sed off" when she came out as transgender, and claimed the pair haven't spoken for "five or six years."
"We were really close, I raised her since she was five years old, I really don't know what her issues are," she lamented.
