Khloe Kardashian "doesn't care" when she dies.
The 31-year-old reality star stunned her mother Kris Jenner when she refused to undergo testing to determine whether she might carry the gene which would put her at risk of contracting breast cancer, insisting she wasn't interested in having the knowledge.
After Khloe refused the test, Kris asked: "'You don't care if you could possibly get breast cancer?"
Her daughter yelled in response: "We're all going to die."
Kris argued: "Do you want to die when you're 30 or do you want to die when you're 85?"
Khloe replied: "I don't care, I don't care."
Kris, 60, also encouraged older daughters Kim Kardashian West and Kourtney Kardashian to undertake the tests, admitting it would be a "great feeling" if they did.
But she was particularly upset by Khloe's refusal because the 'Kocktails With Khloe' star has previously had a cancer scare.
Speaking in a preview for the next episode of 'Keeping Up With the Kardashians', she said: "Khloe has always been very resistant to any kind of test.
"But out of all of us Khloe is the one that needs to have her blood drawn, because she had a brush with skin cancer."
Kim, Khloe and Kourtney's father, Robert Kardashian, died in 2003 just eight weeks after being diagnosed with cancer.
