People.com Entertainment TV Caitlyn Jenner Calls Kris Not Inviting Her to Kylie's Graduation 'a Slap in the Face' "Listen, usually people who get a divorce don't do everything together," Kris Jenner told her ex By Michele Corriston Published on September 10, 2015 10:30 AM Share Tweet Pin Email Photo: Getty; Rich Fury/Invision/AP Caitlyn Jenner and ex-wife Kris Jenner are still struggling to co-parent in a new clip from their first meeting since the Olympian’s transition. In the I Am Cait video via E! News, the former couple argues over Caitlyn’s exclusion from daughter Kylie Jenner‘s high school graduation. “It wasn’t me making that decision. It was you making that decision,” says Caitlyn, 65. “For 15 years of my life, carpooled kids every day. Some days, I spent three or four hours a day in the car. [It’s] a slap in the face when you don’t even get invited to their graduation.” Kris, 59, brings up Caitlyn’s controversial Vanity Fair story before countering, “Listen, usually people who get a divorce don’t do everything together. It wasn’t malicious.” The Kardashians threw Kylie, 18, and her sister Kendall Jenner, 19, a surprise graduation party in late July at Kris’ Calabasas mansion. Caitlyn and Kris married in 1991 and finalized their divorce last December. I Am Cait airs Sunday at 8 p.m. ET on E!
