Isabela Ferrer Opens Up About Working with ‘Angel’ Blake Lively in ‘It Ends with Us’

Isabela Ferrer believes her It Ends With Us costar Blake Lively is “an angel.”

Ferrer recalls exclusively to PEOPLE about when she first met Lively and what it was like to portray the actress’ younger counterpart in the new romantic drama.

When Ferrer, 24, met Lively for the first time, she thought, “This is the most beautiful woman I think I’ve ever seen in my whole life,” she tells PEOPLE at the Tuesday, Aug. 6, premiere of the film in New York. “Then she greeted me with the warmest hug ever, and from then on, it was just wonderful warmth and friendship.”

After describing Lively as “an angel,” Ferrer says, “To be able to connect with the person that you’re sharing a role with is huge, and she’s just a really good person.”

She also notes that both women “understood that support is so important, especially through a process like this and especially with a book like this.” 

Lively stars as Lily Bloom in the film adaptation of the 2016 novel of the same name by Colleen Hoover. Ferrer, who previously starred in an episode of Evil, plays a younger version of Lily.

Ferrer also tells PEOPLE that what surprised her most about Lively, 36, is “how she manages four children with the businesses that she has and [her] career as an actor and a producer and everything else.”

Lively and husband Ryan Reynolds share daughters James, 9, Inez, 7, and Betty, 4, and son Olin, 18 months.

“I mean, she is Wonder Woman,” Ferrer says of the Gossip Girl alum. “I don’t know how she does it. It’s crazy.”

Ferrer continues to admire Lively, noting how she juggles all her titles “with such grace.”

“Yeah, I couldn’t do it personally,” she jokingly concludes.

Ferrer also brought up Lively’s relationship with Reynolds, explaining that while she didn’t see him on the It Ends with Us set, she thinks the Deadpool & Wolverine star, 47, is “a gem” and “such a good person.”

The married couple of 12 years are the “sweetest,” “gorgeous together” and a “power couple,” Ferrer says.

“It’s not even like a lie,” she tells PEOPLE before adding, “I’m saying it first hand.”

Meanwhile, Lively exclusively tells PEOPLE that “it’s the best” to have Reynolds at the premiere with her, and that she is “so grateful” to feel the support of her loved ones — including her mother, Elaine, and sisters Robyn and Lori — at the event, Lively says.

On the red carpet, Lively paid homage to Britney Spears by wearing a vintage Versace gown the “Lucky” singer originally wore in 2002. She also exclusively confirms with PEOPLE the dress is the “actual” gown Spears wore over 20 years ago. 

Along with Lively, Ferrer and Reynolds, the three were joined by It Ends with Us castmates Justin Baldoni, Brandon Sklenar, Jenny Slate, Hasan Minhaj and Alex Neustaedter, as well as the book’s author, Hoover.
