Guess Which O.C. Star Is Now Joining The Hills
TV worlds are colliding: Fans of The O.C. and The Hills are in for a real treat. Us Weekly reports that Mischa Barton is confirmed to join the cast of MTV's The Hills: New Beginnings, which was first announced back in August. She'll join other cast members of the reboot, which include Whitney Port, Audrina Patridge, Spencer and Heidi Pratt, and Justin Brescia (a.k.a Justin Bobby).
Per Us Weekly, the new role "is going to document her comeback. Hopefully people will see her in a new light and not just because of personal problems in the years past." Barton never appeared in the original show, but as People points out, The O.C. was said to have inspired Laguna Beach, which later spun off to The Hills starring Lauren Conrad, so the news isn't as surprising as you might think. Stay tuned as we learn more about the reboot—in the meantime, scroll down to revisit our favorite throwback looks in honor of the news.

After nearly three years at R29, she came back to WWW in 2015, where she is now the Associate Director of Fashion News.
