Catherine Zeta-Jones has checked into a Connecticut hospital for bipolar II disorder.
Her rep tells ET, "After dealing with the stress of the past year, Catherine made the decision to check in to a mental health facility for a brief stay to treat her bipolar II disorder.
She's feeling great and looking forward to starting work this week on her two upcoming films."
Catherine, who stood by husband Michael Douglas' side during his battle with throat cancer last year, has reportedly checked into Silver Hill Hospital in Connecticut.
In February, Catherine made headlines when she was caught on tape lashing out at the paparazzi when she claimed that one of the photographers hit her while in London.
