Mischa Barton and Rachel Bilson may be a long ways away from their days on The O.C., but that doesn't change how they feel about each other. From her living room, Bilson was there to cheer Barton on during her Monday night debut on season 22 of Dancing with the Stars. "Got to give it up for @mischamazing takes balls. Get it guurrrrlll!" Bilson wrote on Instagram alongside a snap of Barton dancing across her television screen.
Barton and Bilson costarred as BFFs Marissa Cooper and Summer Roberts, respectively, on Fox's hit teen drama, The O.C., from 2003 to 2007.
Barton and her partner Artem Chigvintsev tore up the floor with a dramatic tango performance to "In the Night" by The Weeknd that unfortunately only garnered 16 points from the judges.
"It's really tough," Barton told the judges. "He's a tough teacher, which is a good thing, but it's been a road."
