Ariana could be seen looking emotional in a video uploaded to X, formerly Twitter, on Sunday night.

Billie performed her song after receiving an Oscar for best original song.

In the video, Billie sang the emotional song alongside her brother, Finneas O’Connell.

The lavish stage was illuminated in pink to represent Barbie.

Billie wore a black tweed jacket over a white buttoned shirt.

She fastened a pink bow at the collar and completed the look with a skin-tight pencil skirt.

“Wow,” Billie said in shock after she finished singing.

At the end of the performance, the camera panned around to the audience to get their reactions.

The singer received a standing ovation for her efforts.

Barbie director Greta Gerwig also looked emotional while clapping.

The camera focused in on Kate, who played Weird Barbie in the movie.

She wore a black blazer jacket and lightly styled her blond locks.

“Yeah,” she shouted loudly while nodding her head and clapping.

EMOTIONAL ARI

The camera cut from Kate’s passionate reaction over to Ariana.

She wore a pink gown with a huge puff shawl over her arms.

Ariana could be seen crying while clapping for Billie.

She spoke to an unknown man at her side and pulled an emotional face.

Ariana cheered loudly before the camera turned back to Billie on stage.

Fans flooded the comments with appreciation for the emotional performance.

“I still can’t listen to this song without crying. I love this song and she absolutely killed it,” wrote a follower.

“Something about Billie going ‘woah!’ and Kate McKinnon looking like a PROUD MOM had me,” added another.

“If Kate McKinnon is your own personal cheerleader, you’ve already won,” said a third.

“[Ariana] is such a supportive queen,” noted a fourth.

KENERGY

Billie’s performance was not the only Barbie number to steal the show on Sunday, with Ryan Gosling performing his song I’m Just Ken.

Barbie was nominated for eight Oscars – including Best Original Song and Best Picture – but was most swept away by rival Oppenheimer.

Ryan, who played Ken, gave a star-studded performance during the show.

At the beginning of his performance, he stunned in a pink suit while sitting in his seat while his co-star Margot was spotted laughing in front of him.

Ryan was joined on stage by several backup dancers in suits and cowboy hats – and his fellow Kens: Simu Liu, Ncuti Gatwa, Kingsley Ben-Adir, and Scott Evans.

Ryan was even joined by Guns N’ Roses guitar legend, Slash.

The La La Land actor had help singing the song from Greta, Margot, America Ferrera, and even former co-star Emma Stone.

“Behold, the greatest moment in Oscar history!! Bravo, Ryan and I’m Just Ken,” said an X fan.

“Ryan Gosling that performance was kind of everything to me,” exclaimed a second.

“I hope the Kenergy never leaves Ryan Gosling,” noted a third.
