Jonathan Rhys Meyers was reportedly hospitalized in London this week, following a possible suicide attempt.
His spokespeople had no immediate comment on the story, originally published by the UK tabloid The Sun.
Meyers, 33, stars as King Henry VIII in Showtime's popular series, "The Tudors." The actor was found on the floor of his home on Tuesday by paramedics who said that the actor refused treatment and was believed to have taken pills, The Sun and other news outlets said.
The Irish actor has battled alcohol abuse and been arrested for being drunk in public in the past. Sources close to the actor said that Meyers was drinking heavily but was not trying to kill himself.
"He did relapse but he did not try to commit suicide," a source told People magazine. "He was taken to the hospital and then released."
Paramedics at the scene called the police after Meyers continued to refuse treatment.
"We can confirm we were called by the London Ambulance Service to an address in NW8 to report to a man refusing treatment," a Scotland Yard spokesman told People. "Police attended, and the man was taken by ambulance to a central London hospital. That was the end of our involvement."
The actor was reportedly discharged early in the morning on Wednesday.
The Sun said that Meyers recently attended a five-star rehabilitation center in South Africa, which marks the actors fifth stint in rehab.
Meyers is best known for his roles in "Match Point," "Bend It Like Beckham" and "Velvet Goldmine."
