Derek took to Instagram posting a photo of a pool filled with beach balls. Along with the pic, he wrote, "Had a blast dancing in the flash mob at the @svedka party tonight #svedkasplash." The things we would do to watch Derek and Julianne shake it in a flash mob!
And that's not all. Julianne also posted a photo on Instagram showing off her gaming skills. In the pic, she and a friend are playing with a life size Jenga set! This is our kind of party.
Check out the photos from the event and then sound off in the comments!
