When Lily Collins and Ashley Park met while filming “Emily in Paris,” they may not have predicted their onscreen friendship would transform into a lasting bond in real life.

Now, the co-stars call themselves best friends and Park even played a special role at Collins’ wedding to Charlie McDowell in 2021.

“Ashley sang at our wedding,” Collins told TODAY lifestyle contributor Jill Martin during an interview in Venice while promoting Season 5 of their hit Netflix series.

“It was for a really meaningful part of the ceremony, and that was probably the most nervous and honored I’ve ever been,” Park, who is also a Tony-nominated performer, told TODAY.com in a separate interview.

“Her voice was absolutely stunning,” Collins added.

Park, who plays Mindy Chen in “Emily in Paris,” first met her co-star turned bestie when Collins had recently started dating her now-husband.

“I saw her get engaged, then she got married, and now she’s a mom. So for me, I can’t believe we get to do this. And yes, we’re in Venice, but it’s really cool to do with your best friend,” she told Martin.

Collins feels the same way and said she developed a strong connection with Park immediately after meeting her.

“It was a magnetic experience right away — like soul sistership right off the bat,” she said.

For Collins, getting to share in the success of “Emily in Paris” with her bestie makes life even sweeter.

“When you’re doing it with a best friend and like a sister, it becomes a life experience that I don’t think we were expecting back then,” she said. “It’s more than just a show. It’s like this has been our lives for six years, and we’ve gone through so many ups and downs together that this feels like a celebration of not only just like a fifth season, but of the sisterhood, and that’s really special.”

“We feel so grounded with each other,” Park added.

Collins and Park have become so embedded in each other’s lives that they have an inexplicable connection, according to Collins.

“We always start crying when we get emotional because if (Park) feels something, I feel it. It’s very strange,” she said.

“You were in Copenhagen, like last week, and we were talking about something. I can feel any sort of emotion from her and vice versa. And we feel it even from across the world,” Park added.
