Julianne and Derek Hough are notoriously close, but they don’t just hang out with each other. The Dancing With the Stars pros have a lot of celebrity friends, and they recently went on vacation with two of their favs, looking gorgeous on the beach... riding horses. Ain’t no party like a Hough party!

Though their trip was a week ago, Derek didn’t get around to Instagramming this amazing picture until yesterday. One person is very familiar considering she’s Julianne’s BFF (The Vampire DiariesNina Dobrev), but there’s another celeb pal we didn’t expect to see — former That ‘70s Show star Topher Grace!

Alas, he’s sitting next to Nina, mugging for the camera. He’s also the only person with a shirt on out of the bunch. Derek is shirtless, per usual, and the girls are all wearing teeny tiny bikinis, and everyone looks excited and sun-kissed as they ride horses down the beach. Wish we were there!
