Danny Pintauro, who played Jonathan on "Who's the Boss," told Oprah he's been living with HIV for a long time.

The 39-year-old taped a segment for "Where are they Now?" and said he's had the virus for at least 12 years.

Danny was 8 when he played Jonathan on the Tony Danza sitcom.  He had a rough time afterward ... dealing with a crystal meth addiction.

Danny married Wil Tabares last year.
