But the real excitement came when Rossellini finally met Michelle Williams. The Grammy-winning Destiny's Child singer is playing Viola Van Horn on stage, the character based on Rosselini's Lisle Von Rhuman in the film.

"They were so cute together," a source on the scene tells PEOPLE. "Michelle came out all shy and Isabella just embraced her with such warmth and kindness. They both gushed over each other and then everyone sort of let them have a private little moment alone. You could see the conversation meant a lot to both of them."

The energy backstage remained up all night. "Everyone there was gagging over Isabella," says the insider. "She was so sweet and excited to be there, and was game for everything. She took photos with literally everyone. And even grabbed the prop bottle of the youth potion from the show and pretended to drink from it. It was really fun."

Before they departed, Williams, 45, playfully invited Rosselini to step in for her on the show anytime, the source recalls.

Rosselini just might. After all, she already secretly cameos in the musical, having recorded the pre-show announcement welcoming theatergoers to the show and reminding them to silence their cellphones.

That's just one of the many fun Easter Eggs fans can expect in Death Becomes Her. The musical — which features a score from the songwriting team of Julia Mattison and Noel Carey, and a book by Marco Pennette — follows the plot of the film closely, recreating iconic moment after iconic moment from the film including the bulk of its Oscar-winning special effects.

Tony Award-winner Christopher Gattelli directs and choreographs the show, which received rave reviews after it opened at the Lunt-Fontanne Theatre in New York City back in November. It's been a box office smash too through the holiday, propelling it into awards season with plenty of buzz.

Williams is a standout too, delivering her first original Broadway role with powerhouse precision.

Speaking with PEOPLE about the role in December, the actress and singer said she studied the movie after she got the role, almost as "an investigator."

"I knew that I could never be Isabella Rossellini, but I wanted to still capture and respect the integrity of the role [and] still bring me into it," she said.

She nailed it, even earning the praise of her former Destiny's Child bandmates Kelly Rowland and Beyoncé on opening night.

"It was an absolute joy having them there because I know they're fans of the movie," Williams said, noting the three trade lines of the movie they know. "Having them there, I felt anchored. We obviously have not been touring together for years, but it took me back to the time when I'd been with them on stage. Even though they weren't on stage with me, I felt so grounded. It's giving me some fuel for the rest of my run in the show."
