From partying with porn stars to substance abuse and domestic violence, actor Charlie Sheen, who is expected to address rumours that he is HIV-positive on the Today show on Tuesday, is no stranger to controversy.
Here is a brief look at some of the scandalous and shocking news about him over the years.
1990 - He allegedly and accidentally shot his then fiancee Kelly Preston in the arm.
But in 2011, he claimed in an interview that the actress shot herself after "she lifted my pants off the scale in the bathroom…the tiny revolver I used to carry… fell out of the back jeans pocket and hit the floor and shot a bullet right between her legs".
Preston left him after the incident and married actor John Travolta in 1991. In 1990, Sheen checked into rehab for drug and alcohol addiction and hooked up with a porn star.
1995 - Then aged 29, he admitted in videotaped court testimony that he hired "Hollywood Madam" Heidi Fleiss' prostitutes at least 27 times between 1991 and 1993, paying more than US$53,500 in total. Fleiss was then on trial for tax evasion.
1996 - He was charged with assaulting his girlfriend Brittany Ashland, who claimed he grabbed her hair during an argument and pushed her to the floor at his home, knocking her unconscious. He later pleaded guilty and was given a one-year suspended prison sentence.
2005-6 - His wife Denise Richards filed for divorce from him, saying he abused prescription drugs, gambled compulsively, frequented prostitutes and liked to look at pornography on the Internet.
In a custody dispute over their two children later, she claimed he had physically and verbally abused and threatened to kill her - charges that he denied.
2009 - He was arrested after his new wife Brooke Mueller called the police, claiming he threatened her at an Aspen, Colorado, holiday home, during an argument. The real estate investor told the police he straddled her torso on their bed, placed a pocket knife to her throat and his hand around her neck. He later pleaded guilty to a misdemeanor assault charge.
2010 - He was briefly hospitalised after security at a New York hotel called the police, saying he was disorderly and had broken furniture in his room. He was found highly intoxicated and naked in the trashed room.
A porn actress found in the room later accused him of abuse, saying he grabbed her around the neck and threw things at her. His publicist blamed his hospitalisation on an allergic reaction to medication. Days later, Sheen and Mueller filed for divorce.
2011 - He entered rehab again after being hospitalised for abdominal pain following a reported drug- and drink-fuelled party at his home.
Two months later, after a series of public rants against his studio bosses, he was fired from his television show Two And A Half Men. Producer Chuck Lorre later said Sheen was sacked because he was so addicted to cocaine that the show makers feared he might die, or cause someone else to die.
2014 - A dental technician sued him for assault and battery, saying he punched her in the chest during a dental visit.
