Decades of debauchery have finally caught up with one of Hollywood’s top megastars. In a bombshell world exclusive, RadarOnline.com can reveal that a bad-boy Tinseltown star has been hiding an explosive secret from the world: He is HIV-positive. Multiple informed sources confirm the world-famous actor, whom Radar has chosen not to identify, has been diagnosed with the deadly virus that usually leads to AIDS itself. The middle-aged star learned at least two years ago that he had contracted HIV — but he has desperately hidden it from the world, terrified his fans will turn against him.
