Actress Catherine Zeta-Jones is back in treatment for her bipolar disorder.
"Catherine has proactively checked into a health care facility," her rep said.
"Previously Catherine has said that she is committed to periodic care in order to manage her health in an optimum manner."
Meanwhile, another source close to Catherine Zeta-Jones says she was planning to return to treatment as a way for doctors to monitor her medication.
"There was no big problem," says a friend. "This was just a good time to do it. She is in between projects. This has always been part of the plan."
"She would manage her health. She is vigilant about it."
In 2011, Zeta-Jones went to a mental health facility for the disorder, which can cause a cycle of high and low moods, often with episodes of depression.
Nothing seemed amiss a week ago when Zeta-Jones and husband Michael Douglas walked the carpet at the Film Society of Lincoln Center’s 40th Annual Chaplin Award Gala.
On Saturday, Douglas stepped out alone at the White House Correspondents Dinner.
Next up for Zeta-Jones is Red 2, out July 19, with Bruce Willis and Anthony Hopkins.
