Sunday night with a dazzling performance of “I’m Just Ken” from last summer’s blockbuster “Barbie.”

Gosling, a Best Supporting Actor nominee for his portrayal of Ken in “Barbie,” seemingly brought the sleepy ceremony back to life by delivering a high-octane rendition of the Best Song contender.

There were a few more surprises in store, too. As “I’m Just Ken” reached its crescendo, Guns ’N Roses guitarist Slash and Wolfgang Van Halen, son of late rocker Eddie Van Halen, appeared onstage to accompany Gosling for the remainder of the song.
