As they prepared for their facial treatments, Kris opened up in a solo interview about how she still is adjusting to being friends with her ex.
"Because I don't see Caitlyn that often, it takes me a second to digest and absorb that this is the person who I was married to for 23 years," she said. "I'm trying to get used to the new normal for me."
As they laid in adjacent beds, having a gold treatment applied to their faces and necks, Kris recounted how Caitlyn used to shy away from similar activities.
"I remember you used to hate to get your nails done, or your hair cut. Or take a shower," she recalled.
"I'm telling you, Kris, this girl thing is a lot of work," Caitlyn said.
Later, Caitlyn took Kris up on her offer of wine, and brought a copy of her book along for her ex to check out. The pair shared a friendly but somewhat awkward dinner, and it was clear that Kris was still struggling to adapt.
Despite their somewhat bitter past and still-guarded demeanors, Kris couldn't help but be optimistic about what the little get-together represented.
"I think it's a really positive step in a great direction," she mused.
However, she had something of a change of heart when she actually read through the book, only to discover that she had a reason to feel anxiety about the memoir.
"I read it and basically the only nice thing she had to say was that I was great socially at a party one time," Kris told her daughters, Kim and Khloe Kardashian. "None of it makes sense. Everything she says is all made up."
