Julianne Hough and Nina Dobrev are best friends, but they took their relationship to a whole new level during a recent outing. The dancer shared a photo with her bestie and their friend, Milissa Sears, in which they're all showing off their bare butts to the entire world! She appropriately captioned the pic, "Full moons! ???"

Their excursion seems to be a part of a larger trip with friends, and they're having the most fun together.

Sure, it's a little cheeky that they're showing off their rear ends, but it's in a very playful way.
