Catherine Zeta-Jones has checked herself back into a mental health facility for her bipolar disorder.
A statement from her rep says, "Catherine has proactively checked into a health care facility. Previously, Catherine has said that she is committed to periodic care in order to manage her health in an optimum manner."
Last December, Zeta-Jones spoke about going public with her illness with ABC's Elizabeth Vargas.
"I never wanted this to come out publicly. It came out. So, I dealt with this in the best way I could, and that was saying, 'Hey, look, I'm bi-polar.' "
Psychiatrist Charles Sophy says it's good that she's gone public with it.
Dr. Sophy said, "I think that's a great thing because I think, if anything, it's going to lower her stress. Because then she has nothing to hide, she's an open book, she's very clear about it. She knows that she has it. She embraces it, and she's probably not even aware of how many people she's helping by breaking down that stigma."
