The family matriarch has opened up on Kanye West's unique gift for Kim Kardashian West's 40th birthday, which featured a special message from her late father - who sadly died in 2003 when he lost his battle with cancer - who had been recreated as a CGI person.

Speaking on SiriusXM's 'Andy Cohen Live', she said: "We just all started to cry. It was, you know, intense ... It was just, it was really good.

"[Kanye] is the king of gifts and he worked on that for a really long time. So it was definitely one of the most incredible things I've ever seen. It was really wild.

"It was very quiet and we were all in tears and all you could hear was each other crying. It was, it was really, really emotional ... And then, yeah, it was the first thing we wanted to do was see it again and again and again."

The 64-year-old reality star admitted she had to have some time to herself to digest seeing her late ex-husband speaking as a hologram, but described the experience as "beautiful".

She added: "I literally had to go back to my room and just sit there because I needed to digest that and just all that.

"It was intense and it was a beautiful, beautiful moment. So I just wanted to kind of enjoy that."

And Kris dismissed her family's critics after Kim decided to share the emotional birthday gift with her social media followers.

She argued: "We learned a long time ago to have thick skin. You can't really worry about people that are hating all the time and so miserable, and feel the need to reach out and say ugly things ... Just either enjoy it and appreciate the moment or don't. We just can't get into who's thinking what."
