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.

Cillian Murphy won the Oscar for best actor for his role in "Oppenheimer."

The actor, who portrayed physicist J. Robert Oppenheimer, the father of the atomic bomb, in "Oppenheimer," said he was "overwhelmed" to have won the award.

"I'm a very proud Irishman standing here tonight," he said. "We made a film about the man who created the atomic bomb and, for better or for worse, we're all living in Oppenheimer's world, so I would really like to dedicate this to peacemakers everywhere."

Murphy accepted the Oscar from a group of previous best actor winners, including Nicolas Cage, Matthew McConaughey, Brendan Fraser, Ben Kingsley and Forest Whitaker.

This awards season, Murphy has won a Golden Globe, a Screen Actors Guild Award and a BAFTA.

Other nominees in the category included Bradley Cooper for "Maestro," Colman Domingo for "Rustin," Paul Giamatti for "The Holdovers" and Jeffrey Wright for "American Fiction."
