For years, the media called the Kardashians 'talentless' celebrities. But Kylie Jenner is no ordinary Kardashian as she is one of the most famous teenagers in the world, and is now building her own cosmetics empire.

The reality star's brand Kylie Cosmetics has stunned the beauty industry by earning a whopping $420m (£323m) over the last 18 months. And, to celebrate her success and her last day as a teen, Jenner shared her image on Instagram.

The soon to be 20-year-old lip kit mogul wore a peach colored two-piece tiny bikini highlighting her curvaceous body as she lounged by the pool at her mother Kris Jenner's mansion. "Day at Mommy's," she captioned the sexy photo as she relaxed under the sun.

The Life of Kylie star shared another image of hers standing by the pool, revealing her 'sculpted' figure. While the makeup mogul continues to deny that she had breast implants and other surgical procedures, her images tell another story.

Her famous mother, Kris Jenner believes Kylie would become a billionaire by the time she is 25. Kris gushed about her daughter as a 'game changer' in the makeup industry and shared an image from the duo's interview with Women's Wear Daily.

"What an honor to be on your cover WWD! I am beyond proud of my baby... She is not only beautiful inside and out but intelligent, smart, creative, innovative, intuitive and loves her relationship with her fans...You are a game changer Kylie and have disrupted the industry you are so passionate about. You work tirelessly every single day and your work ethic is second to none. BRAVO!!!! I love you," the 61-year-old keeping Up With The Kardashian star wrote.

Adding more to her earnings, Kylie, who will celebrate her 20th birthday on 10 August, launched a special birthday collection, which was sold out within a day and raked $10 million.
