Mischa Barton’s publicist said the British actress, who was hospitalized on a psychiatric hold in Los Angeles last week, is “making improvements.”

Barton, 23, has starred in TV’s “The O.C.,” as well as the movies “St. Trinian’s” and “The Homecoming.”

People.com quoted Barton’s representative as saying the actress is “making improvements” and is “still seeking treatment” without offering any specific details about her illness or condition.

Barton is expected to return to work soon on The CW’s new series “The Beautiful Life,” the publicist added.
