They were among a starry crowd that included Hillary Clinton, John Kerry, Rami Malek, Rita Moreno, Celia Keenan-Bolger, John Benjamin Hickey, Sydney Lemmon, Andrew Burnap and Hamish Linklater.

Bellamy Young was there, too, reuniting with her costar from Scandal, Kate Burton, who is also in the play.

Radcliffe, 36, and Darke, 41, have long supported one another’s careers. Last October, he was by her side at the opening of another play she was starring in at the time: the Off-Broadway production of Vladimir at the Manhattan Theatre Club in New York City.

He’ll next be on stage in February 2026, leading the Broadway premiere of Every Brilliant Thing, the acclaimed solo play by Duncan Macmillan with Jonny Donahoe.

The couple first met on the set of the 2013 film Kill Your Darlings, in which they played lovers onscreen — and found a real-life connection offscreen, too.

“It’ll be a hell of a story to tell our kids one day because of what our characters do with each other,” Radcliffe told PEOPLE in 2019, referencing the love scene they filmed for the movie. “Our characters are meeting and flirting with each other, so there is this kind of sweet record of us just meeting for the first time and flirting.”

In April 2023, Radcliffe and Darke welcomed their first child together, a baby boy, whose name they’ve kept private. Radcliffe revealed to PEOPLE at the 2024 Tony Awards in June that their son is “doing great,” sharing proudly, “He’s talking and saying, you know, nonsense, but very, very charming nonsense.”

That same night, Radcliffe won his first Tony Award for his role in Merrily We Roll Along, and gave an emotional shoutout to Darke and their son during his acceptance speech. “My love Erin — you and our son are the best thing that has ever happened to me,” he said. “I love you so much, thank you so much.”

Darke, watching from the audience, was visibly moved to tears.
