Kylie Jenner's mind was blown when she saw the queue to enter her Kylie Cosmetics pop up store.

The 19-year-old 'Keeping Up With the Kardashians' star - who built up her beauty empire for two years prior to launching it earlier this year - opened her first temporary shop over the weekend and has admitted she was ''amazed'' by the amount of people who flocked to get their hands on her Lip Kits ''on the first day''.

Speaking on her website thekyliejenner.com about the big unveil, which took place at Westfield Topanga Mall in California, she said: ''My Kylie Cosmetics pop-up shop just opened at the Westfield Topanga Mall and I could not believe the crowd on the first day!

''You guys always amaze me and the line of people before we even opened blew my mind.''

Prior to the store's opening the beauty mogul shared a picture of the interior on social media, which sees shelves upon shelves fully stocked with every lip liner and lipstick duo in her ever expanding collection.

She captioned the Instagram post: ''POP UP @ Topanga Westfield LA .. Will I see you there ;) thanks @shopify for making my vision come to life !! #poweredbyshopify (sic).''

The television personality also launched The Kylie Shop over the weekend, which stocks a variety of bomber jackets, crop top and matching knickers underwear sets, a variety of slogan t-shirts, phone cases and badges, which was available both online and in the pop-up store.

And Kylie has revealed ''almost everything'' from her fashion and accessories range sold out online within just one day.

Alongside a picture of a black t-shirt with her sporting a skimpy bra emblazoned on the front of the garment, which she previously posted on the photo-sharing site, she wrote: ''We are sold out of almost everything on @thekylieshop online !!! Wow! Thank you guys for making this launch so special. Check out KylieJennerShop.com to see what's left. Xoxo (sic).''
