Ben Platt engaged to Noah Galvin, who replaced him in ‘Dear Evan Hansen’ on Broadway

They’re bonded for forever.

Broadway stars Ben Platt and Noah Galvin are engaged, the couple announced via Instagram Friday.

“He agreed to hang out forever,” Platt, 29, captioned a series of photos, including the couple holding each other with lights and flowers set up behind them at Laser Wolf Brooklyn.

“I said yeehaw and then cried for like 7 hours,” Galvin, 28, captioned his post.

Galvin — also known for his role in Olivia Wilde’s directorial debut, “Booksmart” — replaced Platt in the titular role of the six-time Tony-winning musical this time in 2017, and romance found the two friends in the ensuing years.

Galvin in May 2020 announced to the world that he and Platt were in a relationship.

“Ben and I are dating,” he told Ilana Levine’s “Little Known Facts” podcast at the time. “I asked him this morning. I was like, ‘Are we allowed to talk about this?’ And he’s like, ‘Don’t go into our like nitty-gritty, but like yeah, people can know.”
