Kourtney Kardashian will reportedly start her makeup company to compete with her younger sister, Kylie Jenner.

According to TMZ, the 38-year-old “Keeping Up With the Kardashians” star filed legal documents to own the name “Kourt” under her company, 2Die4Kourt. The publication noted that Kardashian will be starting her own cosmetics line since she realized that it’s a profitable business.

Jenner’s Kylie Cosmetics have become a huge success, and there are predictions that the company will become even more successful this year. Kylie Cosmetics could be worth $1 billion dollars in five to 10 years. At present, the cosmetics mogul has 500 to 600 people working for her, according to Kris Jenner.

Kardashian and Jenner aren’t the only two members of the Kardashian-Jenner clan who has a cosmetics line. Kim Kardashian also has the KKW Beauty, which stands for Kim Kardashian West.

At present, Kim is promoting her $32 Ultralight Beams Duo, $48 Crème Contour & Highlight Kit, $52 Powder Contour and Highlight Kit and $45 KKW Crème Liquid Lipstick Collection on her website. The 36-year-old mom of three has also launched her KKW Fragrance.

Meanwhile, Jenner is busy working behind the scenes for her cosmetics brand. The reality TV star is rumored to have already given birth. But Jenner is expected to actually give birth to her first child – a girl – sometime next month or early March.

Kardashian, on other hand, is also busy taking care of her three kids with her ex-boyfriend, Scott Disick. Mason, 8, Penelope, 5, and Reign, 3, spent time with their mom at the day spa last week. Mason and his mom also visited a yogurt shop earlier this week after he and Penelope had dinner with their dad.

Kim also welcomed her third child – via surrogate – on Monday, Jan. 15. She made the official announcement via her website. The name of Kim’s baby girl hasn’t been revealed, and her first photos will most likely be released two months from now.
