Bruce Jenner was left in tears when Kris Jenner told him he was no longer the ex ecutor of her will.

Speaking on Sunday's 'KUWTK' episode, Kris says: "For my entire marriage with Bruce he has always been listed as the ex ecutor on my living will.

"But when Bruce and I got divorced I decided that Kourtney was going to be the ex ecutor."

Kris reveals the news to Bruce at a medical facility, where she is undergoing a procedure, after she is asked by a member of staff who should be contacted if there are any complications.

He fails to hide his emotion following the showbiz matriarch's revelation that Kourtney is now the ex ecutor of her will, and disagrees with Kris' decision.

He says: "The problem I have with all of this … Kourtney with the final say? What, I'm not here? I'm the only one here. She's not here."

But the 59-year-old reality star clarifies her decision, insisting she doesn't see why Bruce - who she was married to for 24 years until their divorce was finalised earlier this year - should have that authority anymore.

She explains: "If somebody needs to make a decision, like taking you off life support, we're divorced. "I don't think you should be the one that would decide."

Bruce is in the process of transitioning into a woman but his gender transition is said to have hit Kris hard. An insider recently said: "(Kris) just couldn't emotionally handle it all when he finally came out with it.

"Regardless of whatever signs there were, it's a really hard pill to swallow. She truly went through a mourning period. And they really don't talk now."
