Gaten Matarazzo Got "Emotional" When Sadie Sink and Maya Hawke Surprised Him at His Show

Gaten Matarazzo's first "Dear Evan Hansen" show doubled as a mini "Stranger Things" cast reunion. Costars Sadie Sink and Maya Hawke attended Matarazzo's opening night for the Tony-winning Broadway musical on July 19 to watch him portray Hansen's family friend Jared Kleinman on stage. Now, Matarazzo is opening up about what his friends' support meant to him.

"I didn't even know they were there," Matarazzo told POPSUGAR about his friends' appearance while promoting his new Paramount+ film "Honor Society." "Just to see them there was like the icing on the cake. They were just so ecstatic for me. It just almost made me very, very emotional. And I don't think they know that, how much it really meant to me, but I'll text them."

Matarazzo added that the whole cast are always really supportive of each other's projects. "Caleb [McLaughlin] was just working back to back on two projects in different cities, and it's just crazy to see him just doing incredible stuff."

After the show wrapped and Matarazzo took his first of many bows to come, the trio snapped a few photos together to satiate "Stranger Things" fans in the wake of season four.

The next morning, Hawke praised Matarazzo's performance on social media, sharing a photo of her Playbill on her Instagram Story and writing, "Go see @gatenm123 be just about the most delightful creature to grace the stage." Considering the fact that Matarazzo has appeared in several Broadway productions through the years — including "Priscilla, Queen of the Desert" in 2011 and "Les Misérables" in 2014 — we're hardly surprised to hear he's crushing his latest stage role.

During a recent appearance on "The Tonight Show," Matarazzo discussed his highly anticipated return to Broadway. When host Jimmy Fallon asked if it could be likened to riding a bicycle, the 19-year-old star offered another metaphor. "This is kind of like getting on a motorcycle," he joked. "I haven't run in a show long term consistently since I was 12, and that was before my voice changed. I was only doing four shows a week then, now I'm doing eight."

Matarazzo, Sink, and Hawke appear in seasons three and four of "Stranger Things," portraying Dustin Henderson, Max Mayfield, and Robin Buckley, respectively. In the most recent season, they appear in several scenes together as they track down Joseph Quinn's Eddie Munson before the police do.
