Demi Lovato Tweets Support for Catherine Zeta-Jones

Catherine Zeta-Jones went public with her battle against depression earlier this week, and young star Demi Lovato has her back. Lovato, who recently completed a stint in a rehab facility for unspecified mental and emotional hardships, Tweeted her support of the actress.

She wrote: "I don't know Catherine Zeta-Jones personally but what she has decided to do it SO brave.. And SO difficult but worth it... I'm proud of her"

Catherine has revealed that she checked into the Silver Hill Hospital in Connecticut last week where she was being treated for Bipolar II disorder. She was there for five days, and was said to be suffering from a huge amount of stress related to caring for husband Michael Douglas, who lost 32 pounds in the last year while fending off throat cancer. 

Catherine's representative said: "After dealing with the stress of the past year, Catherine made the decision to check in to a mental health facility for a brief stay."

For her part, Demi recently thanked her fans for helping her get through the "darkest" time in her life. On Thursday she emphasized that it was important for people to be in touch with their emotions.

"Never be ashamed of what you feel," she wrote. "You have the right to feel any emotion that you want, and to do what makes you happy. That's my life motto."
