Catherine Zeta-Jones and Michael Douglas might not get a divorce, even though the two are taking a break from their marriage. Douglas, 69, told Jay Leno on “The Tonight Show” that he was “hopeful” his marriage would work out.

"I've been away for a while, but everything should hopefully be on the up and up," Douglas said on the late-night talk show, according to TV Guide. "Sometimes people take a little bit of a break, but it doesn't necessarily mean that's the end. So I'm very hopeful."

During the 65th Primetime Emmy Awards in Los Angeles on Sept. 22, the actor thanked Zeta-Jones when he won the award for Outstanding Lead Actor In a Miniseries or a Movie for his role in HBO's film "Behind the Candelabra.” "I want to thank my wife, Catherine, for her support,” Douglas said, even though he showed up to the ceremony without her.

Zeta-Jones has apparently been having a difficult time; last spring, she actress admitted herself into rehab to treat her bipolar II disorder. After it was revealed she and Douglas were on a “break,” friends were worried about her “mental health.”

“The next few weeks will be very tough, and I’m very worried about her,” television host Anna Walker told the Daily Mail in early September. “This is a very traumatic time, and her mental health could be adversely affected.”

Zeta-Jones and Douglas continued to make headlines after he said during an interview that he reportedly got throat cancer from performing cunnilingus. “ … without wanting to get too specific, this particular cancer is caused by HPV [human papillomavirus], which actually comes about from cunnilingus,” Douglas said.

He continued: “I did worry if the stress caused by my son’s incarceration didn’t help trigger it. But, yeah, it’s a sexually transmitted disease that causes cancer. And if you have it, cunnilingus is also the best cure for it.”

The celebrity duo share the same birthday, but Douglas is 25 years older. They’ve been married for 13 years have and two children together, ages 13 and 10.
