Party girls!

On Sunday night Kylie Jenner arrived at the London hotel in West Hollywood for the Paper Towns after party, and she was joined by sister Kendall and Selena Gomez. The group was there to support model-turned-actress Cara Delevingne, and Kendall was even photographed holding hands with her BFF on the way in to the bash.

Of course, the only thing anyone is talking about is that WILD Instagram video Kylie posted online last night, in which she dances provocatively and grabs her breasts. Breasts that look suspiciously larger these days...

Back in June, Kylie denied that she had gotten her boobs done and stated in a video that it was just a matter of strategic tape placement. "So whoever thinks I have breast implants, there's a whole load of tape in here holding these up," she said. Show us the tape! And also, maybe wait until you're 18 to start partying in Hollywood?
