Catherine Zeta-Jones completes treatment

Catherine Zeta-Jones has completed her latest treatment for Bipolar II disorder and has returned home, according to husband Michael Douglas.

While promoting his HBO film, "Behind the Candelabra" at the Cannes Film Festival in France, Douglas told People that his wife was returning home on Tuesday.

"She's doing a really good job of getting balanced. I'm proud of her," he said.

The 43-year-old actress proactively checked into a treatment facility for the second time in April for Bipolar II, a disorder known to cause mood swings and erratic behavior. She first revealed that she was diagnosed with the disorder in 2011.

Zeta-Jones can next be seen in the action sequel "Red 2," co-starring Bruce Willis, Helen Mirren, Anthony Hopkins and John Malkovich, which opens July 19.
