Avengers star Scarlett Johansson and Saturday Night Live writer Colin Jost made their red carpet debut on Monday night.

The Avengers: Infinity War premiered in Los Angeles on Monday night and will premiere worldwide on Friday. Johansson shared that the whole experience with the franchise sometimes does not feel real. “I feel like I know why everybody else is here but I never, a decade ago, could ever have possibly imagined anything of this scope with this following. It’s absolutely insane and magical and mind-blowing,” she confessed to Entertainment Weekly.

While it was a monumental moment for Marvel, it was also a big day for the couple as it was their first red carpet debut after almost a year of dating. They first confirmed their relationship in December 2017 while attending an event at the American Museum of Natural History.

On the red carpet, Johansson opted for a metallic silver dress that was embroidered with pearls and crystals from Jimmy Choo, while Jost went with a classic black tux.

The Black Widow actress was thrilled to have Jost alongside her at the premiere because this is the first time she’ll see the movie completed. “I’m just excited to share this experience with him because I’m so excited to see the film. I haven’t seen it before!” she says.

When Jost was asked about her, he admitted he was very lucky. “She’s wonderful. She’s pretty cool… It’s hard to have a lot of complaints, she’s pretty awesome,” he gushed. “The first time she hosted was the first year I was a writer on the show. So, we’ve kind of known each other since then… she’s the best.”

Johansson was previous married to Ryan Reynolds from 2008 to 2011. She also has a daughter, Rose, with her second ex-husband Romain Dauriac, they finalized their divorce just last year.
