The 'Keeping Up With the Kardashians' star, 18, made her line of matte lip liners and liquid lipsticks available for purchase at 12pm and, shortly afterwards, her website LipKitByKylie.com crashed due to the influx of traffic.

The line - which features three colours named Dolce K, Candy K, and TrueBrown K - sold out within minutes, leaving fans, eager to replicate Kylie's plump pout, disappointed.

The stunning products retailed at $29 but are now being sold on eBay for 10 times the price at $255 for just one colour.

Kylie's decision to release a lip line came just months after she was slammed with criticism for undergoing a non-surgical cosmetic procedure to plump up her pout.

The brunette babe was forced to reveal she has had temporary lip enhancement injections on an episode of their family E! reality TV show in May after the #KylieJennerChallenge, which saw young fans attempt to mimic her lip look by sucking on the rim of a cup, went viral.

Earlier this year, she confirmed: "I have had temporary lip fillers. It's just something I wanted to do."

Her mother Kris Jenner, 60, previously admitted she didn't give the reality TV star, who was 17 at the time, permission to get lip fillers and was fuming when she found out.
