Kylie Jenner Turns 20: Kardashian Sisters Respond To Lip Kit Star's Birthday

Newly minted 20-year-old and established beauty mogul celebrated her August 10 birthday with family and friends Wednesday at a surprise party in Los Angeles. The event, thrown by her famous sisters and attended by a number of high-profile guests, was documented across their Snapchat and Instagram accounts throughout the evening. The famed family took to social media again Thursday to share their birthday wishes for the lip kit star.

Kim Kardashian on Thursday took to Instagram, her preferred method of communication, to wish her younger sister a happy birthday while commending her entrepreneurial prowess. The photo featured a bikini-clad Kylie Jenner lounging under a sun umbrella.

“Happy Birthday baby sis!” she wrote for her 102 million followers. “You are always so determined & so set on what you want in life & starting at such a young age you always went for it. That's so inspiring to watch. I love you Ky.”

While Kendall Jenner remained mostly silent on her younger sister’s birthday Thursday — opting instead to promote her upcoming ad campaign with Adidas — the model and reality star did shout-out the beauty mogul Wednesday on Twitter. Quoting a tweet that mentioned Kylie Jenner’s WWD cover and projected $1 billion beauty empire, Kendall wrote, “f—k yeah! BOSSY.”

Indeed, Kylie Jenner’s WWD cover story revealed the youngest of the Kardashian clan has much to celebrate, as Kris Jenner revealed to the magazine that retail sales of Kylie Cosmetics products stood at $420 million in just 18 months on the market.
