According to a bizarre conspiracy theory, Jackson faked his own death and has been working as an impersonator to keep his head down.
A video has made fans demand lookalike Sergio Cortes get the test done to prove their theory.
Barcelona-born Sergio has amassed a huge following online thanks to his MJ videos and performs his songs at gigs around the world.
He has the same curly black hair and striking features that his idol had.
In the video, he says: “Hello to all Michael Jackson fans, come and watch me perform at Hollywood Pattaya on December 23rd.
“I love you guys and see you there. I am Sergio Cortes, see you soon.”
Fans have flooded the clip’s comments with pleas that he prove that he’s not the real Jackson.
One commented: “Oh my god, you’re not Sergio Cortes, you’re Michael Jackson. Someone get his DNA.”
“I need a DNA test, I’m sorry,” another posted.
A third said: “This is the best impersonation I’ve seen of Michael as far as looks.”
“I almost dropped my phone, that’s him y’all,” another agreed.
Another commented: “MICHAEL is BACK! Praise Jesus, Mary and Joseph!”
Jackson died when he overdosed on a cocktail of persecution drugs just weeks before he was due to begin a massive 50-date run of shows at the O2 Arena.
