Their joint line is called KOKO by Kylie Cosmetics, and Khloe referred to this month’s new items as ‘Round 3’.

It just so happens that Khloe left Tristan after he shared a kiss at a party with Kylie’s former best friend Jordyn Woods.

Khloe is the co-founder of the jeans brand Good American and used Jordyn as a model for the company in order to help the latter get started as a model.
