Kylie Jenner's Birthday Celebration Included Twerking in the Mirror

Proud owner of a $6 million mansion Kylie Jenner is in celebration mode.

The youngest Jenner sister turns 19 today. As part of her birthday festivities, she's launched a limited edition and hella expensive Kylie Cosmetics birthday collection, received such extravagant gifts as a car and a puppy and even debuted a bright red wig on Instagram.

KyKy has also been spotted twerking in the mirror, as one might do on one's birthday(?), and, well, we'll just leave it here for your viewing.

To use the words of Janelle Monae as heard on her song "Q.U.E.E.N.", "Is it peculiar that she twerk in the mirror?" I'm gonna go ahead and say no, it's not. Like, at all. (I don't know, is it?)

Let the wig maven / birthday girl do her thing. We're sure Tyga doesn't mind.

VH1 staffers bring Kylie Jenner and Tyga’s relationship timeline to life in the following video.
