HOLLYWOOD trainwreck Charlie Sheen was caught on video smoking crack and performing oral sex on another man in 2011, the same year he was diagnosed with HIV, according to an online report.

The former Two and a Half Men star smoked a crack pipe before grinning for the camera and then pleasuring his male lover, said the website RadarOnline, claiming it viewed a bootleg copy of the tape.

The video had been part of a $US20 million lawsuit against Sheen alleging he gave his sex partner herpes, the site said. The lawsuit was eventually settled out of court for millions of dollars, according to Radar.

The website quotes from the “J. Roe v. John Doe” lawsuit saying an “A-list celebrity,’’ identified by sources as Sheen, “entered into a nefarious plot designed to lure Plaintiff into his luxurious hotel room to serve his prurient desires”.

Sheen allegedly told the man he had “no venereal diseases,’’ and the pair then watched porn and engaged in “mutual oral copulation, mutual self-gratification, rubbing and massaging each other, play-wrestling, licking and (unprotected) intercourse”.

Sheen was given the original video and two other sex tapes involving himself as part of the settlement and ordered them destroyed, Radar said. Radar said it saw a bootleg copy made off the original.

Sheen had met the man in Vegas in April 2011.

The Wall Street actor has said he only found out he was HIV-positive sometime after early May of the same year.
