Former O.C. star Mischa Barton is making improvements and is likely to return to work in a week, says her publicist.
According to China Daily, spokesman Craig Schneider said that the 23-year-old actress is "still seeking treatment but making improvements."
However, he refused to elaborate on Barton's condition.
A CW spokesman for the show, which stars Barton as a pill-popping supermodel, said production was scheduled to begin July 31.
