Ariana Grande Dishes On Her Big 'Don't Look Up' Performance 

Singer Ariana Grande is opening up about her big scene in the Adam McKay climate change comedy, "Don't Look Up."

The film is now the second-most-watched film in Netflix history. Earlier this month, it passed the record by Sandra Bullock's thriller "Bird Box." However, it wasn't enough to pass the crime comedy "Red Notice," which features an all-star cast of superhero actors: "Black Adam" Dwayne Johnson, "Deadpool" Ryan Reynolds, and "Wonder Woman" Gal Gadot.

Although that ensemble is hard to beat, "Don't Look Up" also features an impressive star-studded cast consisting of Jennifer Lawrence, Leonardo DiCaprio, Meryl Streep, Jonah Hill, Cate Blanchett, Timothée Chalamet, Chris Evans, and a performance by Ariana Grande.

The film tells the story of two astronomers (Lawrence and DiCaprio) from Michigan State who start on a media tour to warn the public that an approaching comet is about to destroy the planet after the President (Streep) and her son (Hill) tell them to “sit tight” with the information until after the mid-term elections are over.

In an interview with Variety, the "thank you, next" singer talked about how the stand-out song from the movie came to be.

The hit song from the movie, "Just Look Up," is on the Oscar shortlist and is expected to earn an official nomination when the nominations are announced in February.

Composer Nicholas Britell and lyricist Taura Stinson worked together with Grande, who played pop princess Riley Bina, and KidCudi, who played her on-screen boyfriend DJ Chello.

Grande has already been cast in the film when McKay decided that she should perform as well.

"I was imagining it as a power ballad in a sense, a very strong, very powerful song of hope about love, and then a rallying cry," Britell said.

Britell said that he met with Grande and gave her the outline of the track. "About 30 seconds later, she essentially laid down the entire top line vocal," he recalled. "It was one of the most remarkable things I’d ever seen."

Grande added, "He sent me into the booth to try a melody pass and that ended up being the pass that we wrote the lyrics to."

"It was really fun to hold up a mirror and acknowledge some of the ridiculousness that is so real in this world and what comes with it," she added.

After they had that down, they reached out to Stinson, who had previously collaborated with Britell on the Florence + The Machine song in "Cruella."

Stinson said that creating a "believable love song with the whole world ending in a disaster" was "a bit of a challenge."

"But Ariana’s melody and Nick’s musical bed were so beautiful, and [the film] was such a great inspiration for everything that’s going on in the world, it was easier to write than a lot of songs," she added.

Grande also had a lot of fun improvising a few lines in the film, especially the lyric "You're about the die soon, everybody."

Although Grande stole the show, Kid Cudi was happy to set Grande up for what would ultimately become the message of the movie.

Kid Cudi said that his character is "reconciling after a big breakup, and the world is ending [while] he’s having this special moment with the girl of his dreams."

His rap interlude ultimately sets up the movie's main message: "get your head out of your a-- and listen to the god---- qualified scientists!"
