In the newly-released clip to promote her forthcoming show, Caitlyn is seen showing Kim around her walk-in wardrobe, revealing some of her latest purchases.
Caitlyn shows off her new dress
However, when she proudly displays a newly-bought black dress, Kim - unable to hide her smirk - delivers the blow “Mom has that”, referring to Caitlyn’s ex-wife, Kris Jenner.
Caitlyn was married to Kris for over 20 years, back when she was still known in the public eye as Bruce, but the two split in 2013, and Kris filed for divorce a year later.
A legal requirement meant it took six months for their divorce to become finalised, after which Caitlyn came out as transgender, revealing herself to the world in an already-iconic photo-shoot with Vanity Fair magazine.
Kris recently voiced for support for the photo-shoot, describing the pictures as “beautiful”, and adding: “I think it's amazing. I think that someone following their dream is truly inspirational to a lot of people.”
‘I Am Cait’ is to debut on the E! network later this month, and we can tell already that it’s going to be one of the TV moments of the year.
In the first teaser clip for the reality series, Caitlyn is seen describing having her make-up done professionally for the first time, while in another trailer, she talks about what viewers can expect from the series, including “riding a motorcycle” and “going shopping for the first time”.
