Derek Hough and Mark Ballas are spending their break from Dancing With the Stars the right way — with an intense game night and jam sesh, of course!

The DWTS pros got together earlier in the week, kicking back with some music, cards, and good company. Documenting the evening, Derek took to Instagram showing off a video of him and Mark rocking out to a friend playing guitar. Derek wrote, "Little jam after a successful game night. Cards against humanity and catchphrase, serious competition."

Check out the video below to see Derek and Mark getting their groove on during game night. Who do you think won the big competition? Weigh in below!
