John Cena bares all to present award for best costume
Actor John Cena was among a star-studded list of presenters at the 96th Oscars.
And he made a bold outfit choice to present the award for best costume design, stripping down to mark 50 years since a streaker interrupted the 1974 awards show.
He was joined on stage by Emmy-winning host Jimmy Kimmel, who offered him the winners' envelope to cover up before stepping out to the microphone.
Aussie actor Chris Hemsworth was among a celeb-filled presenters line-up alongside Jennifer Lawrence, Matthew McConaughey, Nicolas Cage, Jamie Lee Curtis, Al Pacino, Lupita Nyong'o, Octavia Spencer, Zendaya and more.
Ryan Gosling steals the show with I'm Just Ken
All five original songs nominated at the 2024 Oscars were performed at the ceremony including two songs from blockbuster hit Barbie.
But the stand out was Ryan Gosling reprising his Oscar-nominated supporting role with the ballad I'm Just Ken.
From serenading Barbie (Margot Robbie), to the head-to-toe pink sparkly suit, Gosling even handed the mic to his La La Land co-star Emma Stone for an impromptu singalong from the audience.
How to watch the Oscars in Australia
The ceremony was broadcast live in Australia on Channel 7 and 7Plus from 10am AEDT on March 11, and a replay will air from 8.30pm AEDT.
