Feldstein also shared a pic in her Instagram stories, writing directly to her new fiancée, “@bonnie_chance you make me happier than I knew was possible. i love you.”

The “Impeachment: American Crime Story” star's Hollywood pals congratulated her and Roberts in the comments of her post.

"Congratulations! 🎉✨❤️," wrote "This Is Us" star Chrissy Metz.

"Amazing. Congratulations!!" wrote six-time Tony winner Audra McDonald.

"Beautiful @beaniefeldstein! CONGRATULATIONS!!! ♥️♥️♥️," wrote "Inventing Anna" star Julia Garner.

Feldstein revealed in an April 2022 interview with Vogue that she and Roberts met on the set of“How to Build a Girl," which Roberts produced.

“Bon was the best thing that’s ever happened to me," said Feldstein. "When something comes into your life and shifts the tectonic plates in such a crazy, incredible way there’s no question for me that I wasn’t going to be open about it."

“And I was lucky to grow up in a family that was incredibly inclusive and understanding,” she added of her family's acceptance of the pair's same-sex relationship.

The couple made their red-carpet debut in December 2019 at the world premiere of Broadway's "Cats" at New York's Lincoln Center.

In August 2021, Feldstein opened up about her relationship with Roberts on Dax Shepard’s “Armchair Expert" podcast.

“We just spent every day together,” she gushed. “It was like, let’s have breakfast at 9 a.m. and then it would be 11 p.m. and we would be like, ‘I guess it’s not breakfast anymore and we’re still staring at each other and talking.’”
