Kris Jenner got yet another shock of her life after Caitlyn Jenner, previously know as Bruce Jenner, threw a bombshell on the the Kardashian matriarch regarding her gender change on the birth certificate.

The big revelation jolted the 60-year-old reality TV star, who is now left pondering over the legality of her marriage to the former Olympian. In the newly released teaser of I am Cait, the episode shows tense conversation between the former couple which eventually leads to a dramatic scene.

While Kris was talking about how she built up Bruce's wardrobe just to throw it after 23 years of hard work, Cait tried gathering courage to face former wife for the big news.

"For the last four, five months, I had lawyers and people going through name change, and I finally got my driver's license," she said, revealing the new initials Caitlyn Marie and stressing on gender column which now reads F.

Kris was completely stunt on what she just heard and replied: "Wow, I didn't know they could do that."

Caitlyn further added: "You can go all the way back to your birth certificate and change that, and I did."

Meanwhile, Kris got emotional and questioned the 66-year-old about the existence of Bruce Jenner, and whether she was married ever. She said: "Does this mean he didn't exist since you changed the birth certificate? Wait, was I ever married? Was I ever legally married?"
