Scarlett Johansson and Colin Jost are red carpet official!

The two made their debut amid a sea of flashes at the premiere of Avengers: Infinity War in Hollywood, California, on Monday night.

While the lovebirds have attended events together, their latest outing marked the first time they have posed together on a red carpet and Johansson admitted she was “excited” to have Jost, 35, by her side.

“It was alright. It was not bad, you know -- get some laughs in and enjoy it,” the 33-year-old actress told ET. “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!”

The two were first linked in May, then attended Dave Chappelle’s birthday bash in New York City with friends in August.

In November, Johansson -- who has a 4-year-daughter with ex-husband, Romain Dauriac -- posed for photos with her SNL beau inside the American Museum of Natural History Gala.

It’s no surprise that Johansson was thrilled to share the Avengers: Infinity War premiere night with her man, given how thrilled she is to have been able to work on the film.

“I often ask myself, ‘How did I get here?’” the Ghost in the Shell star confessed about the superhero film, which hits theaters on Apr. 27. “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.”
