Not a little girl anymore. In the early morning hours of Sunday, July 19, Kylie Jenner posted a raunchy new video via Instagram. The blue-haired reality star, 17, attended the Los Angeles premiere of the upcoming film Paper Towns to support her pal Cara Delevingne

Along with older sis Kendall Jenner, Kylie had more than her fair share of fun at the film's afterparty, getting rowdy with the star of the John Green movie. 

"These didn't make it to Snapchat so here you are Instagram," Kylie captioned the video, which featured her wearing a tan bra and jacket. 

In the clip she grabbed her breasts, stuck out her tongue, danced, and shimmied with Delevingne (in Forevermark jewels) while sitting at a table with several drinks in front of them. 

Kylie recently poked fun at her new mature look, posting a throwback photo of herself from Keeping Up With the Kardashians with her quote, "I promise that I won't grow up too fast." 

"Dammit, Kylie!" she jokingly wrote.
