Catherine Zeta-Jones never complains she's depressed: Michael Douglas

While praising Catherine Zeta-Jones for her support during his cancer battle, Michael Douglas has revealed that his actress wife had never ‘'complained' she was struggling to cope.

The Wall Street actor said Zeta-Jones - who earlier this year spent time as an in patient at the Silver Hill Hospital in New Canaan, Connecticut, to deal with Bipolar II disorder - is now getting better.

"She's doing fine. She's been back working on her movie in Louisiana and she's feeling great,” Contactmusic quoted Douglas as telling Britain's OK! magazine.

"Catherine's a very strong woman and she's had a lot to deal with. She was so supportive and caring of me that she couldn't tell me or anyone else she was having a tough time herself.

"She's not the type of person to complain she's depressed when her husband is fighting cancer," he said.
