Gossip Cop reports that the actress has checked herself into a mental health facility.

"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," her rep confirms.

In addition to her duties as an actress and mother, Zeta-Jones has dealt with more than enough stress in the past few years to merit some much-needed time off and TLC.
