Charlie Sheen is No. 2 on on the list of least trusted personalities in the United States, according to a Reuters/Ipsos poll, whose results were released in August 2011.
About 65 percent of people rated Sheen below average in terms of being someone they trust.
The actor's partying lifestyle, affection for porn stars, rehab stints, firing from the CBS sitcom 'Two and a Half Man' and other personal troubles have made headlines, especially in 2011.
In August 2010, Sheen pleaded guilty to a misdemeanor assault charge regarding a December 2009 confrontation with then-wife Brooke Mueller, mother of his twin sons. He was sentenced to 30 days in a rehabilitation center, 30 days of probation and 36 hours of anger management.
During the following months, Sheen underwent a stint in rehab to treat alcohol and drug abuse and was in March 2011 axed from 'Two and a Half Man,' one of CBS' most successful shows that made him the highest-paid actor on television. The firing occurred just after he insulted show co-creator Chuck Lorre in on-air and online rants. Ashton Kutcher was cast in his place.
Before he was axed, Sheen was suspended from the show. He appeared on various news programs, touting his "winning," party-loving lifestyle and live-in girlfriends, or "goddesses." The actor maintained he was sober, dubbed himself a "rock star from Mars" and demanded a pay raise.
