Kylie Jenner didn't become a billionaire overnight — a look back at her career timeline

It all started back in 2007 when Kylie Jenner made her debut on "Keeping Up With the Kardashians." While mainly playing second fiddle to Kim, Khloé and Kourtney, Kylie teamed up with sis Kendall to become a dynamic duo in their own right. Together they released products their fans went wild for including jewelry, shoes and nail polish. The two even wrote a sci-fi novel together, Rebels: City of Indra: The Story of Lex and Livia. In 2015, Kylie Lip Kits launched promising fans at home the secret to getting their very own version of Jenner’s signature smile. Three years later, Forbes magazine declared her the youngest-ever self-made billionaire, and she posted a message to her fans saying, “2018 has been unforgettable thanks to you … and having Stormi of course has made it the best. I can’t wait for 2019.” In 2019 the makeup mogul added skin care to her empire with launch of Kylie Skin.
