Confirmed! Oscar winning CATHERINE ZETA-JONES “proactively” checks in to rehab treatment facility to manage her bi-polar disorder.

 “Catherine has proactively checked into a health care facility,” her rep said. “Previously Catherine has said that she is committed to periodic care in order to manage her health in an optimum manner.”

This isn’t the first stint in a treatment center for Michael Douglas‘ 43-year-old wife, who checked in to a hospital two years ago, reported.

It’s unclear where Catherine is receiving her reported 30-day treatment this time, but in April 2011 she stayed at the Silver Hill Hospital in Connecticut.

As The ENQUIRER reported previously the stress of dealing with Michel Douglas’ cancer and his incarcerated son Cameron is causing quite a strain and the Welsh-born  beauty knows when to seek medical assistance for her condition.
