“Keeping Up With the Kardashians” star Kylie Jenner has certainly learned something from her older sisters. Weeks after she turned 18, the youngest Kardashian-Jenner sister launched her own makeup line, Lip Kit by Kylie. But there’s a problem: Her lipsticks sold out in a matter of seconds and the LipKitbyKylie.com site crashed.

Angry fans, who presumably want to duplicate her enviable pout, tweeted angry messages at the star. “So the Internet has been broken lol. But everybody stand by. There are so many people on the site right now we are having some tech issues! We are working on it,” she wrote Monday, 30 minutes after three shades from her lip kit dropped.

Though the site went back up, no more lip kits remained in stock. All three varieties -- Candy K (light pink), Dolce K (light beige) and True Brown K (dark brown) -- could no longer be purchased, at least for now.

Jenner revealed Monday evening that more shades from her lip kit line would be available in time for Christmas. “I'm so sad they sold out so fast. Don't be upset! This isn't exclusive. There is more to come & still a chance to buy before Christmas!” she wrote. “Stay tuned. I love you guys.”

The best way to know when Jenner will sell more lip kits is to check her social media pages. She announced the makeup line on Snapchat and Instagram a day before they went on sale.

Keep in mind there are some scams out there. The lip kit retails for $29.00, but there are some netizens who are reselling it for more than 10 times the price on sites like Amazon and eBay.

After years of denial, Jenner finally admitted that she used temporary injections to plump her pout during Season 10 of “KUWTK” in May. “I have had temporary lip fillers,” she said. “It's just something that I wanted to do.”
