Michael Douglas supports Catherine Zeta-Jones

London: Husband Michael Douglas is fully supporting Catherine Zeta-Jones and her decision to enter treatment for her bipolar II disorder for a second time.

The 68-year-old actor is by her Welsh actress wife of twelve years, who is expected to complete a 30-day program as a `proactive` measure to help with her condition, which can cause high and low mood swings as well as depression, reported Contactmusic. A friend close to the couple said, "He couldn`t be more supportive, just like she is of him. They`re solid. They are really, really devoted to each other." The couple, who have been rumoured to split several times this year, were last seen together in New York at the Film Society of Lincoln Centre`s 40th Annual Chaplin Award Gala. Zeta-Jones, who has two children, Carys, 10, and Dylan, 12, with Douglas, first sought medical help in 2011 when she spent time in a Connecticut-based mental health facility. Her spokesperson Cece Yorke confirmed that she re-entered treatment in recent days. PTI
