Ryan Gosling, the little liar, was prepping "I'm Just Ken" Oscars performance for "months"

“He was pretty clear about his overall structure of it,” told Variety. “He wanted to start in the audience, come up see Mark, see Andrew [Wyatt the co-producer], ignite the Ken-delabras and then join the 10 dejected Kens on the stairs,” she said. “From there he wanted the rest of the number to evolve as if Kens were coming from everywhere, ‘Calling All Kens.’ Eventually ending in a huge celebration revealing Slash.”

Rehearsals for the performance began four weeks ago (during which time Gosling was lying about not being invited, natch). But certain elements didn’t come together until the last minute. The other Kens (Ncuti Gatwa, Simu Liu, Scott Evans, and Kingsley Ben-Adir) had just two days to learn the dance. “I flew in from London on Thursday, and hit that stage. Mandy Moore kept us going,” Gatwa told the outlet. And Slash didn’t fly in until day-of. But it all paid off in a show stopping number that, although the track didn’t take home the Best Original Song trophy, was pretty much beloved by all.

According to Moore, after it was over Gosling gave her “a huge hug” backstage, “And then he got all serious, and asked, ‘Were shots right? Did I do a good job?’ I’m like, ‘Yes! Oh, my God, are [you] kidding me? Did you hear those people? They were freaking out!’”
