According to TMZ,Joe Jackson says he did not OD on Viagra, and he's ready to sue some media outlets that made the claim.
A rep for Joe tells us the 87-year-old's lawyer has an international media company called RTL in the crosshairs for reporting that Joe's stroke and heart attacks were triggered by too much Viagra.
Other media made similar claims, and Joe's lawyer plans to go after them as well.
The rep says Jackson has hospital records proving there was no Viagra in his system when he was admitted.
Jackson arrived back in the U.S. this week after suffering three heart attacks and a stroke while vacationing in Brazil.
