Mischa Barton, the former O.C. starlet whose troubles with substance abuse have been well chronicled, looks as if she might be out of a job. As you read in our Industry column here on Vulture back in March, she had been cast in the CW show A Beautiful Life as someone who is “struggling to keep on top and is in danger of slipping.†Well, according to Michael “Raisin Bran†Ausiello over at Entertainment Weekly, they should probably change that sentence from present to past tense: The CW is rumored to be on the hunt for a replacement actress, in light of Barton’s recent struggles.
