VIDEO : Julianne Hough Goes Pants-Free!

Julianne Hough and Nina Dobrev decided to celebrate the evening's full moon on Thursday while soaking up the sun in Idaho, with a cheeky moment of their own. Only wearing a string bikini top, Julianne and Nina opted to go sans pants as they gazed out into the distance while on a boat ride. These two sure know how to throw caution to the wind and have a little fun! The entire group documented their trip on Instagram, which included tons of time by the pool, wakeboarding, rope swinging, hiking and boating.
