It is claimed the rocker also shares some genes with ancient Romans and is a distant relative of the outlaw Jesse James, the last Russian tsar Nicholas II and King George I.
The results were found when scientists took some of his blood and sent it to a lab in New Jersey.
They found he shares some of the same DNA of those that were killed in Pompeii in 79AD after Mount Vesuvius erupted.
Osbourne joked: 'That means I'm also probably related to some of the survivors, which makes a lot of sense. If any of the Roman Osbournes drank nearly as much as I used to, they wouldn't have even felt the lava. They could have just walked it off.'
