Whose butts are those?! Well Julianne Hough and Nina Dobrev's of course! The actresses decided to flaunt their bottoms in honor of this full moon it seems!

The besties are currently on a group trip to a lake with some pals and looking they are having a blast -- so much so that they decided to take off their off their pants!

Hough, Dobrev, and actress Milissa Sears dropped their bikini bottoms and took a photo of their pert butts and posted the snap to Instagam. The former Dancing with the Stars pro wrote, "Full moons! 🌝🌝🌝."

We can't image her Mormon relatives loved that one!

The blonde beauty was also featured in a photo posted by the Vampire Diaries star of the two of them hugging in a picturesque spot. Too fun!

The ladies also appeared to be joined by Hough's fiancé Brooks Laich, her brother Derek Hough, and Milissa's husband, actor Teddy Sears.

Reunited at last... 🤗 #SpoonFriendsAreTheBestFriends 📸: @brookslaich
