Life might have imitated art for Mischa Barton. In December 2007, she was arrested for DUI, pot possession and driving without a license, and she was sent to court-ordered rehab. Two years later, Mischa threatened to kill herself after a family intervention, and she was sent to a psych ward on a 5150 hold. Her romantic life has been as chaotic as Marissa's: She's been linked to Brandon Davis, Cisco Adler, Luke Pritchard and Sebastian Knapp, from whom she split in August 2013.
Although she was named an "it girl" during her time on "The O.C.," Mischa's personal struggles significantly slowed her career. In 2009, she starred on short-lived series "The Beautiful Life: TBL." She's also starred in a number of limited-release movies, mostly horror flicks and thrillers. Mischa has also delved into the fashion world. After designing collections for companies like ASOS, she debuted her own clothing and accessories line called Mischa's Place in 2012.
