This created chaos on social media with fans falling head over heels in love with the electrifying performance from their very own Michael.
They rushed to the comments section of various posts to add tributary mentions for the legendary multi-hyphenate star.
One fan commented: "This gave me chills and tears of joy."

A third gushed: "This is freaking beautiful"
While a fourth applauded the celebrity, noting: "He's amazing he's awesome wow the greatest on my time is child watch his movies he will always will be remembered".
