See Caitlyn Jenner confront Kris Jenner over Kylie's graduation

LOS ANGELES, Sept. 10 (UPI) -- Caitlyn Jenner recently confronted ex-wife Kris Jenner over daughter Kylie's high school graduation.

The 65-year-old former olympian sat down with the 59-year-old television personality to discuss her hurt over not being invited to the milestone. Kylie Jenner graduated in July, and Caitlyn's reaction to being excluded will air on Sunday's episode of I Am Cait.

"It wasn't me making that decision, it was you making that decision," the reality star told Kris. "I was so disappointed in everybody. For 15 years of my life I carpooled kids every day ... [it's] a slap in the face when you don't even get invited to their graduation."

Caitlyn and Kris finalized their divorce in December 2014 after a lengthy separation, but will continue to co-parent Kylie and 19-year-old daughter Kendall Jenner. Caitlyn also remains close to her former stepchildren, Kourtney, Kim, Khloe and Rob Kardashian.

Kris suggested she still has lingering hurt feelings over Caitlyn's now-famous Vanity Fair article in the episode preview. The reality star covered the July 2015 issue of the magazine after coming out as a transgender woman in a 20/20 interview in April.
