Mischa Barton gets cozy with her "Hills" co-stars.
Mischa posted a selfie on Instagram Saturday between two of her costars on the upcoming "The Hills" reboot, Audrina Patridge and Stephanie Pratt.
“On wednesdays we wear whatever we want…and you can totally sit with us,” she captioned the snap, making a winking reference to "Mean Girls."
Stephanie Pratt posted the same pic, writing, "Hanging out in #TheHills 💫@audrinapatridge@mischamazing ✨.”
The "O.C" star will be making her reality TV debut with MTV's revival "The Hills: New Beginnings," which is slated to premiere in 2019. The new series will reunite original cast members -- including Brody Jenner, Audrina Patridge, Heidi and Spencer Pratt, and Justin Bobby -- their children and new faces for a look at the private and professional lives in LA.
Mischa confirmed that she had joined the cast in October with an Insta post declaring, “The secret’s out… I’m joining the cast of The Hills.”
She added, "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."
In the video, Mischa whips off her sunglasses and announces, “Welcome to The Hills, b***h!”
The actress never appeared on "The Hills" during its six-season run, but her casting in the reboot makes sense. Mischa rose to fame in 2003 thanks to her role as Marissa Cooper on Fox’s "The O.C.," which inspired MTV’s "Laguna Beach: The Real Orange County," which then spun off into "The Hills" and "The City."
