Catherine Zeta-Jones has completed her treatment for Bipolar II disorder and is ready to come home, according to husband Michael Douglas, who spoke to People at the Cannes Film Festival, where he is promoting his upcoming film "Behind the Candelabra."

"She comes home tomorrow," Douglas said. "She's doing a really good job of getting balanced.

"I'm proud of her," he added. "She's got herself worked out with her meds and she's raring to go!" 

Zeta-Jones, 43, entered a treatment program for the second time when she "proactively" checked herself into a mental health facility on April 29 to complete a 30-day program. She has reportedly completed the program ahead of schedule.

She had previously sought treatment for the disorder in April 2011 and has been open about living with the illness, bringing positive attention by demonstrating that anyone can be afflicted and that it can be managed.

"It's not easy," she previously told InStyle. "I'm not the kind of person who likes to shout out my personal issues from the rooftops, but with my bipolar becoming public, I hope fellow sufferers will know it's completely controllable.

"I hope I can help remove any stigma attached to it, and that those who don't have it under control will seek help with all that is available to treat it," she said.

Zeta-Jones entered the treatment program as her husband was beginning to earn praise as he promoted the upcoming HBO film.

"She loves it," Douglas said. "It cracks her up.

"She thinks it's a great movie," he continued.

The film co-stars Matt Damon as Liberace's lover, which Douglas says gave him a new perspective on the performer's lifestyle.

"He was a very hard-working guy who never seemed to lose his cool," he said. "It was a joy playing a nice guy.

"I don't get to play a lot of nice guys," he added.

Zeta-Jones second stay at a mental health treatment center continues to put personal faces on the illness, coming after Oscar season, when the film "Silver Linings Playbook," with a main character suffering from bipolar disorder brought a lot of public attention to the illness, especially after director David O. Russell discussed his son being the inspiration for him to do the film.

Bipolar II disorder is a mental illness characterized by a period of manic activity followed by a period of major depression.
