The actress starred in The O.C., and because of its popularity, MTV created Laguna Beach: The Real Orange County, and the spin-off The Hills. (Plus, a few other less popular spin-offs, but who’s counting?)
Mischa will reportedly be joining Heidi and Spencer Pratt, Whitney Port, Audrina Patridge, and more stars of the original show!
