Jennifer Lopez can't stop gushing over Lin-Manuel Miranda.
ET caught up with the 46-year-old singer at the Ice Age: Collision Course premiere in Los Angeles on Saturday, where she had nothing but positive things to say about collaborating with the Hamilton creator and star on "Love Makes the World Go Round."
Lopez told ET's Carly Steel that the song, which was penned to benefit the victims of the tragic shooting at Pulse nightclub in Orlando last month, has received an "amazing response."
"When we finished the record, it was put out so quickly," she revealed. "We did it one day, and the next day it was like, 'OK. It was on iTunes.' But I felt like people felt the urgency of it. The record company and everybody involved was like, 'We need to get this out there right now.' It's been an amazing response from not just fans of mine, but people all over the world."
Lopez explained that when she and Miranda originally wrote the song, the lyrics were specifically geared toward the Orlando shooting. Now, she says it's "taken on even more meaning" as there have been "a lot of senseless acts of violence going on," including the terror attacks in Nice, France, that left 84 dead earlier this month.
"It's one of my favorite songs I've ever done," she continued. "When I sing the words, I really feel, I don't know… There's just something different about it than any other song I've ever done. I just feel like the world needs that message right now. The fact that love is the answer. Love is the key. That really makes the world a beautiful place. Makes it go round."
The mother of two also praised Miranda, 36, for his work in his Tony-winning Broadway musical production. Lopez attended his final Hamilton performance at the Richard Rodgers Theatre in New York City with her 8-year-old twins, Emme and Maximillian.
"They knew a lot of the songs," she revealed. "My sister, my whole family [have been] huge Lin-Manuel fans since In the Heights, so with Hamilton, I think we were on to it way before other people were. So, they know a lot of the songs from the musical. They were so excited to be there."
ET also talked to Lopez about the plot of Ice Age: Collision Course, which deals with parents suffering from empty nest syndrome. Even though it will be a long time until her children leave their family home, the brunette beauty confessed she thinks about them venturing out into the world on their own quite often.
"You think about it from the minute they're born, 'Oh, they're gonna leave one day,'" Lopez, who voices the character of Shira in the animated comedy, explained. "Yeah, it's funny."
"It's all about family," she said of the film, which officially hits theaters July 22. "It's all about how you make that family. It's the people in your life that you're born [with], but also people that you acquire along the way, and how important that is. So, I love being a part of it."
Earlier this week, Lopez and Miranda delivered an emotional performance of their new song on The Tonight Show. Hear more in the video below.
