Michael Douglas thanked his estranged wife Catherine Zeta Jones in his acceptance speech for Best Actor in a miniseries or TV movie at last night's Emmy Awards.
"I want to thank my wife Catherine for her support," the actor said as he accepted the honour for his role in Behind the Candelabra.
The 68-year-old Hollywood star and Welsh-born Zeta-Jones, 43, announced in August that they were "taking some time apart to evaluate and work on their marriage."
In recent years, Michael Douglas has battled stage-four throat cancer.
In June, the Hollywood actor hit the headlines when he said his battle against throat cancer was caused by performing by a sexually transmitted disease.
The 68-year-old claimed his stage-four cancer was contracted through the human papilloma virus during oral sex.
Welsh actress Catherine Zeta Jones and her husband Michael Douglas are "taking some time apart", her publicist has said.
The couple married 13 years ago and have two children, Dylan and Carys, together.
Earlier this year, Jones - who shot to fame in the early 1990s playing Mariette Larkin in The Darling Buds Of May - checked into a clinic for treatment of a two bipolar disorder.
She has previously said of the illness: "There is no need to suffer silently and there is no shame in seeking help."
Catherine Zeta Jones and Michael Douglas are "taking some time apart to evaluate and work on their marriage", a statement released by her publicist said.
A publicist representing Michael Douglas has denied that the actor blames a sexually-transmitted disease for his throat cancer.
Allen Burry issued a statement in which he claims Douglas never said that oral sex was the specific cause of the disease.
"In a discussion with the newspaper, they talked about the causes of oral cancer, one of which was oral sex, which is noted and has been known for a while now," Burry said.
But The Guardian newspaper, which originally quoted Douglas in an interview with reporter Xan Brooks, is standing by its story and has published an audio recording of the exchange.
"This particular cancer is caused by something called HPV, which actually comes about from [performing oral sex]," Douglas can be heard to say.
Michael Douglas has spoken about his frustration of not being able to visit his son, who is currently serving time in a federal prison for drug possession and dealing.
"It's been a long haul", he told Daybreak's Richard Arnold, "my oldest son is incarcerated in federal prison, and for much too long of a time.
"Right now I'm dealing with the fact that I'm not allowed to see him for two years which seems kind of punitive on their part, I mean I didn't do anything."
The actor, plays American musician Liberace in his latest film Behind The Candelabra.
