Mischa Barton Poses with “The Hills” Costars

Just a week after confirming that she is joining the cast of MTV’s The Hills revival, Mischa Barton is showing her fans that she fits perfectly in the Californian reality TV world.

The O.C. alum took to Instagram, posting a snap of herself with her new co-stars Audrina Patridge and Stephanie Pratt. The three ladies were all smiles in what is the first behind-the-scenes picture from the set of the revival series. She captioned the snap, with a reference to the iconic Mean Girls writing, “on Wednesdays we wear whatever we want… and you can totally sit with us 💋.”

The switch to reality television comes years after Barton starred in the teenage drama The O.C. Barton played Marissa Copper in the series that became a huge success overnight. The O.C. inspired MTV’s Laguna Beach: The Real Orange County, which eventually spun off into The Hills. She announced her casting on Instagram writing, “secret’s out… I’m joining the cast of The Hills. When MTV approached me with the chance to be a part of the reality show that was inspired by The OC, it felt like the perfect opportunity for an irresistibly inviting new chapter.”

The Hills: New Beginnings will reunite the original cast and their children and will include some new faces as well. It is set to premiere in 2019.
