Kris Jenner broke on our hearts on Sunday night's episode of Keeping Up With the Kardashians.

The 61-year-old sat down with her mother, Mary Jo "M.J." Campbell, to discuss her life experiences — and it wasn't long until the conversation took an unfortunate turn.

Kris asked her mother what her biggest fear was, to which M.J. replied, “I try not to fear. What’s your biggest fear?”

By this point, the momager was in tears.

"I don’t wanna say it. Why did you ask me that? I can’t believe I’m crying. Just losing someone,” she admitted.
