Which actor performed the song 'I'm Just Ken' live at the 2024 Oscars ceremony?

The memorable performance of "I'm Just Ken" at the 2024 Academy Awards was indeed delivered by actor Ryan Gosling. Gosling, who portrayed Ken in the blockbuster film "Barbie," brought his character's signature "Kenergy" to the Oscar stage in a highly anticipated live rendition of the song.

The song "I'm Just Ken" originated from the "Barbie" movie, where it serves as Ken's power ballad, expressing his existential struggles and feelings of being secondary to Barbie. Written by Mark Ronson and Andrew Wyatt, the song became a viral sensation and was nominated for Best Original Song at the Oscars. Gosling's live performance was a highlight of the ceremony, featuring him in a sparkling pink suit, accompanied by numerous backup dancers (including his co-stars Simu Liu, Kingsley Ben-Adir, and Ncuti Gatwa), and even a surprise guitar solo from Slash of Guns N' Roses.

The elaborate and theatrical performance began with Gosling singing from the audience, seated behind Margot Robbie, before transitioning to a vibrant pink stage. It included visual references to Marilyn Monroe's "Diamonds Are a Girl's Best Friend" and saw Gosling engaging with the audience, including director Greta Gerwig and fellow cast members, who sang along. Despite losing the Best Original Song Oscar to Billie Eilish and Finneas's "What Was I Made For?" also from "Barbie," Gosling's energetic and humorous act was widely praised for its entertainment value and became one of the most talked-about moments of the night.
