'My Best Friend's Wedding' Cast Reunites Over 20 Years Later to Reflect on '90s Rom-Com

It's been 22 years since a scheming Julia Roberts tried to steal the man of her dreams away from Cameron Diaz in "My Best Friend's Wedding," but it was nothing but love as the cast reunited for a new EW cover story.

Roberts, Diaz, Dermot Mulroney and Rupert Everett cover the publication's Rom-Com issue (below), celebrating some of the most popular and beloved romantic comedies in film history. Through their conversation, the stars shared some behind the scenes gossip from the movie shoot, while revealing how the project has lived on in the two decades since.

"People come up to me and just say, 'My Best Friend's Wedding!' and I'm like, 'Aww,'' Diaz told the magazine. "It's just this joyous feeling that you get off of them. I appreciate that so much," she added, saying that sister-in-law Nicole Richie is one of those super fans.

"My sister-in-law is obsessed with this movie. We went to Chicago, like, a year and a half ago, and she took me to every single [location]," Diaz revealed. "She's like, 'Remember when you were walking down the street right here and then...' It was so much fun. I was like, 'Yes, I think I do.' She's like, 'I do, and it really means a lot to me, so I would like for you to pretend like you do."

Roberts said she was initially drawn to the film -- which revolves around a woman who makes a pact to marry her best friend if they're both still single at 28 (!), only to see him wed another woman before the deadline -- because of all the physical comedy.

"Lots of falling down and falling through things, falling all over myself, falling over Dermot," she explained. "The scene, for me, that made it feel so authentic and earnest is when I finally tell Dermot's character, 'Pick me. Let me make you happy.' Just that line: That's just so succinct and sweet and meaningful."

Everett and Diaz also both reflected on their respective singing scenes, as Rupert memorably performed Burt Bacharach's "I Say a Little Prayer" and Cam botches "I Just Don't Know What to Do With Myself" at karaoke in the flick.

"I was terrified to do that scene, for real. I allowed the true terror of singing in front of people to be alive in me," recalled Diaz. "I wanted to run and hide, and Dermot kept me there. He said, 'You can do it, you can do it.' In the scene I'm just staring at him the whole time because he's looking at me like, 'You're okay. You're not gonna die.' And I was like, 'But I'm dying."

Everett said his number wasn't originally in the script, but was added just before they started filming. "And then that night [after filming it], I went back with you [looks at Roberts] on the Warner jet to New York, and then I thought I was living the dream," he shared.

Looking back, Everett said watching the film recently "kind of made me cry, just thinking of how magic that time was, that summer."

He added that he believes his and Roberts' characters -- who end the movie with each other -- are "a little bit like Will and Grace" now. As for the other two, Mulroney firmly believes they'd still be together.
