Catherine Zeta-Jones released from treatment for bipolar disorder

Catherine Zeta-Jones was spotted out driving in New York Tuesday, having completely treatment for bipolar II disorder after she checked herself in last month for what her husband, actor Michael Douglas, called her "10,000 mile checkup."

Zeta-Jones first revealed her diagnosis and decision to seek treatment in 2011, and returned to a healthcare facility at the end of April.

"Catherine has proactively checked into a healthcare facility," her representative, Cece Yorke, said. "Previously Catherine has said that she is committed to periodic care in order to manage her health in an optimum manner."

Douglas praised his wife's progress from Cannes, where he is in town to promote his HBO film "Behind the Candelabra."

"She's doing a really good job," he said. "I can't wait to see her. I'm proud of her."
