Robert Downey Jr. has sent his fans into a frenzy after reportedly unfollowing his Marvel co-stars on Instagram.
The actor, 56, recently unfollowed Marvel actors including Tom Holland, 25, and his apparent good friend Chris Evans, 40, which has caused many fans to speculate about what's going on.
He last reprised his role as the superhero Iron Man in the 2019 movie Avengers: Endgame, concluding the Infinity Saga.
The unfollowing comes just days before the release of Scarlett Johansson's first standalone Marvel movie, Black Widow, which is hitting theatres on July 9, per the New York Post.

Reacting to the unfollowing on Twitter, one Marvel fan tweeted Downey Jr., writing: "I don't know what's happening Mr Stark... WHYYY DID YOUU UNFOLLOW THE MARVEL CAST ON INSTAGRAM? [sic]"
A second added: "rdj why did u unfollow the whole marvel cast OPEN UP I JUST WANNA TALK."
A third wrote: "I was curious about Downey's profile on Instagram and I saw that he unfollowed about 20 people and those people were Marvel actors! Robert Downey Jr are you ok?"
However, while Downey Jr.'s actions on Instagram might have sent his fans into meltdown, he still follows his former co-stars on Twitter, where he has since been active.
Now, some have speculated that the unfollowing wasn't the result of a behind-the-scenes Marvel fallout, but the actions of a new social media manager.
One fan tweeted alongside a broken heart emoji: "I think it's a new social manager or something. And it's turning more into a business thing now. He even changed his header on here."
A second agreed, noting that Downey Jr. no longer followers any other actors, writing: "What is wrong with Robert Downey Jr changing his instagram into business account and unfollowing all his friends [sic]."
Then there was this Twitter user who thinks people should have better things to do than monitor who celebrities are following on social media.
They wrote: "The fact that people are publicly freaking out about Robert Downey Jr. unfollowing MCU people on Instagram, as if that is the end-all be-all determinant of someone's friendship with someone else, is why I don't take humanity seriously, by and large. Come on, people."
