Cameron Douglas, son of actor Michael Douglas, has been sentenced to four additional years in prison for taking drugs while in jail. He was originally jailed in April 2010 on a five-year sentence for dealing meth and cocaine ... and possessing heroin.

The 33-year-old inmate reportedly asked the judge to "consider his crime a consequence of drug addiction." In court, Cameron told the judge, "You see your honor, I cannot seem to find comfort in my own skin."

Despite Douglas' plea, the judge said he needed a harsher punishment for his pattern of "reckless, disruptive and non-compliant" behavior.

Combined with his previous sentence, Douglas must now serve nine years total behind bars.

Michael Douglas sat down with Oprah Winfrey in an episode airing today, where he said that wife Catherine Zeta-Jones didn't reveal her struggle with bipolar disorder by choice, but rather she was "outed" by someone in her treatment facility.

“I must say, Catherine’s being quite open about it because she was outed, you know,” Michael told Oprah. “She went to go get some help and some other patient probably in there said, ‘Hey, you won’t believe who’s in here now.’ And, so, once that happens, I think she felt [it] best to kind of get out the story.”

And get it out she did. After spending five days in a treatment facility, Catherine's rep issued a statement earlier this month: "After dealing with the stress of the past year, Catherine made the decision to check into a mental health facility for a brief stay."

Michael defended his wife on the show, saying, "My son is in federal prison, my ex-wife is suing me. . .it's kind of hard for the wife to say that she's depressed."

But now that Michael is cancer-free, Catherine is focusing on her work. "She's great," Michael told Oprah. "She's shooting a movie down in Louisiana, and I think she's relieved she has a better understanding [of bipolar II]."

See what film role has been created just for Catherine ... after the jump.

Michael Douglas is enjoying the brisk New York City air as he walks his daughter Carys to school.

The actor, who is now healthy after a battle with throat cancer, is gearing up for his upcoming role as Liberace ... co-starring Matt Damon as his lover. Production is expected to begin at the end of the year.

Just last week, Michael and wife Catherine Zeta-Jones arrived at their London hotel where a fight broke out involving Zeta-Jones. The gorgeous actress claims a photographer shoved her. Zeta-Jones could be heard saying, "I want a police officer right now. He punched me!"

Glad to see Douglas has put the frightening incident behind him.

Find out why the couple were in London ... after the break.

Michael Douglas and wife Catherine Zeta-Jones were spotted arriving back at their London hotel last night, and as the couple made their way through the entrance, Zeta-Jones freaked out when a photographer allegedly struck her.

Zeta-Jones waited in the lobby and yelled, "I want a police officer right now. He punched me!" and Douglas, who is still recovering from cancer, got very aggressive with the photographer in question. Entertainment Tonight has the video of the actor grabbing the lensman and yelling obscenities, and it all happened so fast, we had to watch the video a few times to see what happened!

The couple were in England to receive an award for Zeta-Jones' charity work, and Douglas' rep tells ET, "You saw it for yourself. Otherwise, the trip and the ceremony were fabulous and such a joy for everyone."

New York fashion week brings out the big guns!

The always stunning Catherine Zeta-Jones, accompanied by her happy and healthy hubby Michael Douglas, attended the Michael Kors show (along with Bette Midler and Angelica Huston) at Lincoln Center in the Big Apple today.

Meanwhile, HSM starlet Vanessa Hudgens showed off her lovely legs while on her way to the Yigal Azrouel show - V-Hud was also out and about in NYC last night! Busy girl.

While in New York preparing for his role as Liberace, Michael Douglas took a break from his busy schedule to enjoy lunch with pals at Marco Restaurant in New York.

The actor was diagnosed with throat cancer last year, and after completing intense radiation and chemotherapy, he looks much healthier ... and even seems to have put on weight. We couldn't be happier for him!

Douglas' wife, Catherine-Zeta Jones, has been by his side from the get-go, and no doubt, that has helped with his recovery.

As for his upcoming role, Douglas admits he's not the best dancer or singer, but he's "going to get my fingers ready for Liberace."

See which A-list actor will be playing Douglas' lover in Liberace after the jump ...
