Catherine Zeta-Jones has checked into a mental health facility for treatment of her bipolar disorder, reports TMZ.
Sources told the website that the 43-year-old actress, who has been open about her personal struggles with the disorder, checked into treatment on Monday and is expected to complete a 30-day program.
A rep for the actress has confirmed that Zeta-Jones has entered treatment, telling the Associated Press in an email that she made the decision to "proactively" seek help, and "is committed to periodic care in order to manage her health in an optimum manner."
"It’s not easy. I’m not the kind of person who likes to shout out my personal issues from the rooftops, but with my bipolar becoming public, I hope fellow sufferers will know it’s completely controllable," Zeta-Jones told InStyle magazine in its December 2012 issue. "I hope I can help remove any stigma attached to it, and that those who don’t have it under control will seek help with all that is available to treat it."
