Why is Selena Gomez violently rocking out in a car showing off her bra?

Last night Selena Gomez shared a video on Instagram of herself gyrating (dancing?) in the front seat of her car with her jacket open revealing her black bra. Why? Good question.

Not that I am complaining, Selena Gomez can do anything involving us getting to see her bra (or a bikini) and I’m cool with it, but it all just seems so odd. As does her shout out that captioned the video, “Hey @chrissyteigen wanna dance off?”

And here I didn’t even realize Selena Gomez and Chrissy Teigen were friends.

Watch and be confused yet aroused at the very same time.
