is once again sitting down with her ex, Kris Jenner, on the next episode of I Am Cait
, where Caitlyn reveals that she's legally had her name and gender changed on her driver's license.
In this sneak peek for the upcoming episode, Caitlyn tells Kris, "For the last four months, five months, I've had lawyers and people going through [the] name change [process]. But I finally got my driver's license."
Caitlyn is clearly excited about the new document, which has her full name -- Caitlyn Marie Jenner -- and "gender marker 'F.'"
Kris, however, appears genuinely shocked
by the news, telling Caitlyn, "Wow, I didn’t know they could do that."
"You can go all that way back to your birth certificate and change that," Caitlyn added, "and I did… my passport is in the process."
This news seems to knock Kris back even more, before the wheels in her head start to turn and she comes to an interesting quandary: "Does this mean [Bruce] didn't exist, if you changed the birth certificate?" Kris asked, half-smiling. "Wait, was I ever married? Was I legally married?"
Caitlyn seems as confounded by the possibility as Kris, but fans will have to wait until Sunday to see how the ramifications of Kris' question play out.
Kris also opens up about how much it upset her when she found out Caitlyn was purging her closet
of the clothes she owned before her transition.
"When Kim [Kardashian] brought me some of your clothes that you were throwing away, I was so sad because I thought, 'Wait a minute, I spent 23 year building this fabulous wardrobe,'" Kris recounted. "Who knew I was buying the wrong s**t?"
After Caitlyn and Kris reunited in New Orleans on the last episode of I Am Cait
, the two seemed to be on more amicable terms after hashing out some tense conversations
about how Caitlyn handled their divorce and her transition.
