Nina Dobrev certainly knows how to celebrate! After going on a safari in Africa with friends for her 30th birthday on Jan. 9, the Fam actress kept the festivities going with a Coachella-themed party in Culver City on Saturday. The event, which was dubbed "Ninachella," brought out a ton of Nina's famous friends including Julianne Hough, Brooks Laich, Vanessa Hudgens, and her former The Vampire Diaries costars, Kayla Ewell and Candice King. Nina looked completely in her element as she drank shots from a guitar, paraded around in her flower crown, and snapped photos in the photo booth. At one point, Zedd took over the DJ booth while Nina rocked out alongside him. Yeah, Coachella is cool and all, but right about now we're wishing we got invited to "Ninachella."
