Queen, Lady Gaga and Bradley Cooper to Perform at the 2019 Oscars -- See the Full List

These are the artists who will take the stage to sing this year's Best Original Song nominees.

There will be plenty of star-studded musical performances at this year's Oscars!

The Academy announced that four Best Original Song nominees that will be performed during the 91st Annual Academy Awards telecast on Sunday, Feb. 24. The fifth nominated song, "All the Stars" from Black Panther, however, will not be performed.

The news that all five nominated artists would be invited to perform was only recently confirmed: Deadline reported that Oscars producers originally planned to only have two songs be performed during the show: "Shallow" from A Star Is Born and "All the Stars." However, the site says either Lady Gaga or her reps made it clear that she felt it would be unfair to leave out the other three nominees.

Here is the full list of performers and the Oscar-nominated songs they will be singing live during the ceremony:

"Shallow" from A Star Is Born, Performed by Lady Gaga and Bradley Cooper

With music and lyrics by Gaga, Mark Ronson, Anthony Rossomando and Andrew Wyatt, "Shallow" has already won a handful of trophies this awards season, including a Golden Globe and GRAMMY. Cooper and Gaga have performed the song live together once already, surprising fans with the duet during the singer's Las Vegas show, Enigma.

ET recently spoke with Cooper and he revealed that he's preparing for his Oscars performance by working with the "incredible" vocal coach who helped find Jackson Maine’s voice in the first place, Roger Love.

"I couldn't sing before this movie and so, in terms of being able to sing in front of people, it's very nerve-racking. It's not easy what they do," Cooper admitted. "We worked tirelessly [to prepare for the movie]. So, I called him and said, I'm back in L.A. on the 15th of February and hopefully I can do it!"

"I'll Fight" from RBG, Performed by Jennifer Hudson

Hudson -- who won an Oscar in 2006 for her supporting role in Dreamgirls -- will take the stage to sing the empowering anthem written by Diane Warren. The track is featured in the Best Documentary Feature nominee RBG, about the life of Supreme Court Justice Ruth Bader Ginsburg.

"When a Cowboy Trades His Spurs for Wings" from The Ballad of Buster Scruggs, Performed by Gillian Welch and David Rawlings

First-time Oscar nominees Welch and Rawlings, who wrote and composed the track, will entertain audiences with the collaboration they created for the Coen Brothers Western dramedy, sung by Tim Blake Nelson in the film.

"The Place Where Lost Things Go" from Mary Poppins Returns, Performed by Bette Midler

With music by Marc Shaiman and lyrics by Scott Wittman and Shaiman, the song is performed by Emily Blunt in the film. However, the actress will not be performing it during the ceremony. Instead, the number will be sung by two-time Oscar nominee and all-around musical legend, Bette Midler.

"So, (drum roll) Ladies and Gentlemen, I will be chanteusing (that's singing) on the Oscars on Feb 24...the nominated song from "Mary Poppins"..."The Place Where Lost Things Go" ...so excited!!" Midler tweeted on Friday, ending speculation over who the "special guest" stepping in for Blunt would be.

"All the Stars" from Black Panther Will Not Be Performed

Though it was previously assumed that Kendrick Lamar and SZA would be on hand to perform the track -- especially considering it was one of the two songs Oscars producers originally intended to feature -- ET has learned that the musicians will not be performing "All the Stars" and that the song will not be performed by another act.

Queen and Adam Lambert Will Perform ???

Though not nominees for Best Original Song, the real-life band behind Bohemian Rhapsody will take the stage with Lambert for an additional performance during the ceremony. "Queen + @adamlambert will ROCK YOU!" the band tweeted, including the show's 5:00p.m. PT start time. Perhaps in the absence of a host, Queen will open this year's show? We'll be tuned in on Sunday to find out.
