All five songs nominated in the best original song category will be performed during the show.

In February, the Academy announced that Becky G, Ryan Gosling, Billie Eilish and more would take the stage. Becky G will perform Diane Warren's "The Fire Inside" from "Flamin' Hot," while Eilish will sing "What Was I Made For?" from "Barbie," which she co-wrote with her brother, Finneas O'Connell.

Gosling will sing the power ballad "I'm Just Ken" from "Barbie." The song was co-written and co-produced by Mark Ronson and Andrew Wyatt.

Also taking the Oscars stage are Jon Batiste, who will perform "It Never Went Away" from "American Symphony," and Scott George, who will perform "Wahzhazhe (A Song For My People)" from "Killers of the Flower Moon" with the Osage Singers.

Academy Award nominees America Ferrera, Billie Eilish and Finneas O'Connell were all smiles as they posed for photos together on the red carpet.

Ferrera, who is nominated for best supporting actress for her performance in "Barbie," stepped out in a pink gown, while Eilish wore a black blazer with a white button down shirt and a black and white skirt with a matching houndstooth purse. O'Connell wore a classic suit with a black bowtie.

Eilish and O'Connell's song "What Was I Made For?" from "Barbie" is nominated tonight for best original song.

Amid the ongoing Israel-Hamas war, "Anatomy of a Fall" actors Milo Machado-Graner and Swann Arlaud wore Palestinian flag pins on the Oscars red carpet.

The five filmmakers nominated in the best director category include Martin Scorsese, Justine Triet, Christopher Nolan, Yorgos Lanthimos and Jonathan Glazer.

Scorsese's nomination for the crime drama "Killers of the Flower Moon" is his 10th best director nomination. He won best director in 2007 for "The Departed."

Nolan, who directed and wrote "Oppenheimer," and Lanthimos, who directed "Poor Things," are up for best director at the Oscars for the second time in their careers.

Triet, who directed and co-wrote "Anatomy of a Fall," and Glazer, who directed and wrote "The Zone of Interest," are first-time Oscar nominees.

"20 Days in Mariupol" won the Oscar for best documentary feature film.

Filmmakers Mstyslav Chernov, Michelle Mizner and Raney Aronson-Rath accepted the award, which was presented by Kate McKinnon and America Ferrera.

"Probably I will be the first director on this stage who will say I wish I had never made this film," Chernov said about his film, which offers a harrowing account of the Russia-Ukraine war. "I wish to be able to exchange this [for] Russia never attacking Ukraine, never occupying our cities. I wish to give all the recognition to Russia for killing tens of thousands of my fellow Ukrainians."

"I wish for them to release all the hostages, all the soldiers who are protecting their lands, all the civilians who are now in their jails, but I cannot change the history," he continued. "I cannot change the past. But we, all together, you ... some of the most talented people in the world, we can make sure that the history record is set straight, and that the truth will prevail -- and that the people of Mariupol and those who have given their lives will never be forgotten. Because cinema forms memories and memories form history."

Other nominees in the category included "Bobi Wine: The People's President," "The Eternal Memory," "Four Daughters" and "To Kill a Tiger."
