Michael Douglas says Catherine Zeta-Jones was "outed" over her treatment for bipolar II disorder at a mental hospital and adds that his wife is now doing "great."
The 41-year-old Oscar-winning Welsh actress spent several days at a Connecticut facility and her spokesperson had said earlier this month that she began her treatment "after dealing with the stress of the past year."
The actress has two children with Douglas, 66, who revealed in August 2010 that he had Stage Four throat cancer. The actor announced in January that he had beaten the disease.
Zeta-Jones talked about her struggle with bipolar II disorder in an interview with People magazine.
"I must say, Catherine's being quite open about it because she was outed, you know," ABC News quoted Douglas as telling Oprah Winfrey on an episode of her syndicated talk show that is set to air on Tuesday, April 26.
"She went to go get some help and some other patient probably in there said, 'Hey, you won't believe who's in here now,'" he added. "And, so, once that happens, I think she felt [it] best to kind of get out the story."
People suffering from bipolar II disorder experience both elevated moods, which may lead to increased activity, and episodes of depression. Their "up" periods are less intense than those experienced by those diagnosed with bipolar I disorder. Both types of ailments can be controlled with medications, including antidepressants, and therapy.
CNN reported that he also told Winfrey that Zeta-Jones is doing "great," adding: "She's shooting a movie down in Louisiana." As for himself, Douglas said his monthly checkups show that he remains cancer-free.
Zeta-Jones is known for movies such as "The Mask of Zorro" and "Chicago," the latter of which earned her an Oscar. Her last film, the R-rated independent movie "The Rebound," had a limited release in 2009.
She recently began shooting the sports comedy "Playing The Field" in Shreveport, Louisiana, People said. The movie also stars Gerard Butler, Jessica Biel, Uma Thurman, Ethan Hawke and Elizabeth Berkley and is set for release in 2012.
Zeta-Jones is also set to star in the comedy movie "Lay the Favorite," which features Bruce Willis and Justin Timberlake and is also set to hit theaters in 2012. On Wednesday, April 20, director Adam Shankman confirmed Zeta-Jones had joined the cast of his musical film "Rock of Ages," which will see her playing an "arch-conservative" villain.
Douglas and Zeta-Jones have been dealing with other problems besides the actor's health - in 2010, a judge sentenced the actor's son Cameron to five years behind bars for dealing methamphetamine. Also that year, Douglas' ex-wife Diandra Douglas began a legal battle to try to claim half of the actors' earnings from the film "Wall Street: Money Never Sleeps."
"My oldest son is in federal prison, my ex-wife is suing me and I got cancer, Douglas told Winfrey. "It's kind of hard for the wife to say that she's depressed."
