Zeta Jones, 41, made a decision to check into a “mental health facility” for a brief stay, said her publicist.
Michael Douglas, who was diagnosed last year, said in January his tumour had gone and he was beating the disease.
Last September, Zeta Jones said she was “furious” that doctors failed to detect the cancer earlier.
Bipolar, also known as manic depression, causes severe mood swings, that usually last several weeks or months.
Zeta Jones’s publicist Cece Yorke said the actress sought treatment for the condition following the stress of her husband’s cancer fight.
