Reality TV star Kourtney Kardashian is set to launch her own range of cosmetics to rival her sisters Kim Kardashian and Kylie Jenner's brands. According to tmz.com, Kourtney has filed legal documents to own the business name "Kourt" but, in order to keep things under wraps for the time being, she filed the application under her company "2Die4Kourt". Although it is not known for sure whether Kourtney will bring out her own cosmetics range, she has been uploading more beauty-related content on her application, including her favourite natural products and her every day make-up routine. Her sister Kylie's range -- Kylie Cosmetics -- keeps expanding year on year, but is known for liquid lipsticks, lip liners, eye-shadow palettes, concealers and foundation. Kim, 37, on the other hand, launched her KKW beauty range in 2016 and just two months ago dropped a line of shimmering highlighters and lip glosses.
