Cheeky! Besties Julianne Hough and Nina Dobrev are having a blast on their group trip to the lake. The pals have been goofing off with close friends, and on Thursday night they even went so far as to strip down together.
In a racy pic, Hough, Dobrev, and actress Milissa Sears ditched their bikini bottoms.

“Full moons!” the Dancing With the Stars alum captioned the shot of the three girls looking over a moonlit lake with their booties half exposed.
Dobrev also shared a photo of herself snuggling with Hough on an outdoor porch, writing, “Reunited at last… #SpoonFriendsAreTheBestFriends.”
The Vampire Diaries alum attempted to go wakeboarding, posting a funny clip of herself to Instagram. She starts off strong before ultimately wiping out (in slow motion!).
“There she is… There she is… There she goes. Bye #Almost #NotQuite #Fail,” Dobrev captioned the video.
It seems Julianne’s older brother, Derek Hough, is also on the trip. The famed dancer took a photo of some of the group on a boat and shared a video of himself doing flips before belly flopping into the lake.

“Double back flip to face plant. First time in a while I got the wind knocked out of me. That kind when you start breathing funny #lakelife#ineedtoTuckTighterandReleaselater,” he captioned the clip, which Dobrev shot.
Derek is preparing to star in Hairspray Live! this December after his younger sis nailed her performance of Sandy in Grease Live last year.
“Grease definitely raised the bar as far as the way it was shot and the way it was done,” Derek told ET earlier this month. “And for this musical, it kind of lends itself to that similar style, I suppose.”
