Despite how badly we didn't want it to end, we knew this day was coming. After Stan Lee passed away last year at age 95, Marvel fans knew his beloved cameos could only continue for so long. Now, according to MashableAvengers: Endgame will mark Lee's final cameo appearance.

We're not ready for it to end.

Previously it was reported that there was a possibility for Lee's cameos to continue past Endgame, at least into the forthcoming Spider-Man: Far From Home.

“We’ll see,” Marvel President Kevin Feige told ET Online. “We’re heading—We shot a couple of others, so we’re coming up on the last of them, yes.”

While it was neither confirmed nor denied that Lee would make an appearance in the film, director Joe Russo put an end to the plaguing question during press day in Los Angeles.

When speaking of Lee's cameo in Avengers: Endgame he tells Mashable, "It’s his last one committed to film."

Our hearts can't handle this.

Anthony Russo reflected on Lee's enjoyable visits to the studio by saying, "We have all these movie stars on that set, and when Stan came to set, everybody would be like kids again," he said. "It was always a lot of fun shooting these cameos because he was very charming, and he would maybe get the crew going, and everybody would be laughing and having a good time."

While it's a bit heartbreaking to imagine that we may soon see the last official Stan Lee cameo in just a few short weeks, it does seem a bit fitting that things would end on Endgame.

"I have to say, I think it’s astonishing that this would be his last cameo," Joe says. "It’s just kind of mind-boggling that he made it to the end of this run. I can’t believe it."
