One of the main stars of the show, Finn Wolfhard, who plays Mike, has hinted that this could be true, after dying his hair purple.
Would he be making such a drastic change to his hair if he had to continue being Mike?!
“I LOVE IT SO F*CKING MUCH THIS IS SO AMAZING YOU LOOK SO GOOD” one fan wrote.
“such a handsome boy,” said another.
“Okkk Finn i love it ……. but I gonna miss the old look”
His makeover comes at the same time ST co-star Millie Bobby Brown completely broke down on Instagram after wrapping season 3.
“Last day of shooting for Stranger Things 3…I will cry all day FYI,” she wrote.
She also said she couldn't “say goodbye” to her costars, and that this was “not okay.”
