A spokeswoman for Catherine Zeta-Jones says the actress has "proactively" checked into a mental health facility for treatment of her bipolar condition, The Associated Press reported.

Publicist Sarah Fuller said in an email to the AP late Monday, April 29 that Zeta-Jones "is committed to periodic care in order to manage her health in an optimum manner."

Two years ago, the 43-year-old Oscar-winner checked into a similar facility for a brief stay for treatment of her condition, known as Bipolar II. The disorder is characterized by mood swings and depressive episodes, and is commonly treated with medication and psychotherapy.

Zeta-Jones has been one of the busiest talents in show business of late, appearing in such films as "Rock of Ages," ''Playing for Keeps," ''Broken City" and "Side Effects."
