Actress Catherine Zeta-Jones is out of rehab following her second stint in the facility -- the first being in 2011 -- for help treating her bi-polar disorder.

While on the red carpet at the Cannes Film Festival, hubby Michael Douglas told reporters that his wife is "doing wonderful," explaining, "She's got herself worked out with her meds."

As for why Zeta-Jones went public with her entry into rehab, Douglas replied of his heroic bride, "There are so many outlets, so it's better you get out in front of it tell your story before it becomes gossip."

Jones has previously been open about her disorder, saying, "If my revelation of having bipolar II has encouraged one person to seek help, then it is worth it. There is no need to suffer silently and there is no shame in seeking help."
