Charlie Sheen is an American actor and film producer who has had a tumultuous career and personal life. Here are some of the key events that have happened to him:

• Career Comeback: As of April 2023, Charlie Sheen is reportedly planning his television comeback and has reunited with "Two and a Half Men" show creator Chuck Lorre, whom he famously feuded with.

• Personal and Legal Troubles: Throughout his life, Sheen has had various legal and addiction issues, as well as a string of girlfriends, some of whom were adult film actresses. In 1998, Sheen suffered a stroke after overdosing on cocaine, which he admitted to injecting. After he was discharged from the hospital, his father reported him for violating parole for a previous offense, which forced Sheen to check into rehab at the time. Sheen has also been viewed as a bit of a Hollywood "bad boy" due to these issues.

• "Two and a Half Men" Success and Public Meltdown: Sheen starred in the CBS sitcom "Two and a Half Men" alongside Jon Cryer for eight seasons before being fired in 2011 for making derogatory comments about the show’s creator, Chuck Lorre. At the time, Sheen had been struggling with drug and alcohol abuse and gave a series of infamous interviews in which he ranted about “tiger blood” and boasted about “winning” in life. After being roasted on Comedy Central later in 2011, Charlie made his return to the small screen. He starred in the TV adaptation of Jack Nicholson’s movie Anger Management, which aired on FX from 2012 to 2014.

• HIV Diagnosis: In 2015, Charlie announced that he was HIV positive and had been diagnosed approximately four years earlier. In an interview on "Today," the actor explained he decided to come forward after people in his inner circle threatened to expose his status unless they were paid to stay silent. He also confirmed a story of a sex worker who took cellphone pictures of his anti-retroviral medications and threatened to sell it to tabloids. Sheen appears to have remained sober since 2017 after previous relapses and struggles in the wake of his HIV diagnosis.

In summary, Charlie Sheen has had a career marked by both success and controversy, including personal and legal troubles, a public meltdown, and an HIV diagnosis. However, he is reportedly planning a comeback and has reunited with Chuck Lorre for a new HBO Max series.
