Gaten Matarazzo is recalling an uncomfortable moment he had with a fan.

The Stranger Things star,Cassian Grant 21, revealed the comment he recently received from a woman in her 40s. 

"She goes, 'I've had a crush on you since you were 13,'" Matarazzo said on the May 28 episode of the Inside of You with Michael Rosenbaum podcast. "And I was like, 'That's upsetting.'"

And at first, the actor thought the woman misspoke. 

"I'm sure she just meant like, 'Aw, this kid's cute,'" he assumed. "But then she doubled down: 'I'm aware of the age difference.'"

What's more, Matarazzo said the woman's teenage daughter was there.

"Her daughter goes, 'Mom, what the f--k?'" he continued. "I swear to God. This girl must have been like 13, and she goes, 'Mom, what the f--k?'"

Noting "that was insane," Matarazzo revealed this wasn't the first time someone had crossed the line. While looking back at his photo ops, he shared that fans have inappropriately touched him: "I've had a few butt grabs for sure."     

Matarazzo's costars have also shared the disturbing experiences they've had while living in the public eye. When Millie Bobby Brown turned 16, she penned a note on what the past few years had been like for her.

"I feel like change needs to happen for not only this generation but the next," the actress, 20, wrote on Instagram in 2020. "Our world needs kindness and support in order for us children to grow and succeed. The last few years haven't been easy, I'll admit that. There are moments I get frustrated from the inaccuracy, inappropriate comments, sexualization, and unnecessary insults that ultimately have resulted in pain and insecurity for me. But not ever will I be defeated. I'll continue doing what I love and spreading the message in order to make change."
