The 'Keeping Up With The Kardashians' star's former husband is said to be transitioning into a woman, with a source revealing that Kris couldn't "emotionally handle" the situation when he announced he would be undergoing gender reassignment surgery.

The insider 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."

Bruce - who had been married to Kris for 24 years before their divorce was finalised in early 2015 - reportedly feels as though Kris is upset she is not "getting her own way" when it comes to the transition.

Another insider added to PEOPLE magazine: "Bruce feels like Kris is used to getting her own way, and going ahead with his transition was not probably part of her plans."

Meanwhile, other sources have revealed the pair are having nothing to do with each other following Bruce's revelation.

An insider said previously: "They don't even talk. She doesn't have anything to do with him, really.

"[She] thinks the transition is Bruce's business to deal with. She doesn't deal with his stuff."
