Kris Jenner Wonders 'Was I Ever Married?' After Caitlyn Jenner Drops Another Transition Bombshell
04/13/2016 AT 02:35 PM EDT
In a preview for Sunday's I Am Cait, Caitlyn's ex-wife Kris Jenner has smaller fish to fry when she brings up that Caitlyn has given away some of the clothes she wore when she was still known as Bruce to daughter Kim Kardashian West.
"I thought, 'Wait a second!" says Kris, 60. "I spent 23 years building this fabulous wardrobe."
She adds with a laugh: "Who knew I was buying the wrong s---?' "
But Caitlyn, 66, has an even bigger bombshell for Kris (whom she divorced in 2014) – she's transitioning all of Bruce's legal documentation.
She reveals that her driver's license is officially now listed as Caitlyn Marie Jenner ("with a gender marker 'F' ").
"You can go all the way back to your birth certificate and change that – and I did," Caitlyn continues. "Passport's in the process. ... I feel like I've come out this other side."
Kris is stunned almost speechless. She takes in all this new information before wondering, "Does this mean he didn't exist? ... Was I ever married? Was I legally married?"
I Am Cait airs Sundays (9 p.m. ET) on E!
