The bizarre pop star proudly accepted what he thought was a massively important award at the MTV Video awards - the Artist of the Millennium.
Except there's no such honour!
The confusion started when Britney Spears introduced him on stage to present him with a cake for his 44th birthday.
Britney said that, for her, Jackson was the artist of the millennium.
He even gave a speech in front of the celeb-packed audience and millions of TV viewers.
He thanked God, his parents and the magician David Blaine.
MTV said it was a all "a bit of a misunderstanding".
