Zeta-Jones bipolar: The actress checked into a mental health facility for treatment of her bipolar condition, according to a spokeswoman.
Publicist Sarah Fuller said in an email to The Associated Press late Monday that Zeta-Jones "is committed to periodic care in order to manage her health in an optimum manner."
The program at the facility will be 30 days, according to TMZ. The actress's last public appearance was April 22, when she hit the red carpet at the 40th Anniversary Chaplin Award Gala at Lincoln Center with husband Michael Douglas.
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.
When asked in December last year about the condition, she told the crew on Good Morning America she didn't want to talk about it.
"You know what? I'm sick of talking about it because I never wanted to be the poster child for this. I never wanted this to come out publicly. It came out," she said. "I dealt with it in the best way I could and that was just saying that, 'Look, hey, I'm bipolar'. Everyone has things going on and we're doing the best we can. We can't jump from the rooftops shouting about, 'I have this, look at me, victim' - no. We all have issues in life and I'm really happy I have great friends, great support and that's all I can do."
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."
