The Oscar-winning Welsh actress, who completed a stint in a US mental-health facility in 2011, is believed to have signed in for a 30-day programme, so doctors could monitor her medication and condition.

Her publicist Cece Yorke confirmed the news to People.com, saying: “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.”

Jones, who starred in Steven Soderbergh’s Side Effects, has admitted the disorder can cause a cycle of high and low moods, and episodes of depression.

She has previously said of the illness: “This is a disorder that affects millions of people and I am one of them. If my revelation of having bipolar II has encouraged one person to seek help, then it is worth it.

“There is no need to suffer silently and there is no shame in seeking help.”

Jones, who will next star in Red 2 alongside Bruce Willis and Dame Helen Mirren, was last seen on the red carpet at awards gala in New York with husband Michael Douglas on April 22.
