Danny Pintauro Tells Oprah What Happened After He Came Out
Pintauro, who starred in the '80s sitcom, Who's The Boss, came out publicly as gay in 1997 after the National Enquirer threatened to out him.
"When I first came out, which was before everybody -- I mean, Ellen and I came out the same year. Rosie came out four years after I did -- I missed the opportunity to be a beacon of light for gay kids who were going through what I was going through," he tells Winfrey.
Not only did Pintauro open up about the heart wrenching struggles that come with being diagnosed HIV-positive, the 39-year-old former child actor also discussed the epidemic of crystal meth use within the gay community.
