39-year-old Johansson wore a long white coat over her black gown, which she paired with matching black pumps and a clutch. The actress added a pop of color to her ensemble with a swipe of red lipstick.

41-year-old Comedian Jost meanwhile also looked dapper in a classic black tuxedo. The smiling pair exchanged loved-up glances as they posed and smiled arm-in-arm for the cameras at the event.
Johansson and Jost tied the knot in 2020 after they were romantically linked in 2017. The pair first met in 2006 on the set of Saturday Night Live, when Jost was in the writer's room and Johansson was hosting an episode.
"They're very much in love. It's serious," a friend of Jost's told PEOPLE in 2017. "They're both very respectful of each other's careers and very supportive. They're super cute together."
Meanwhile, Johansson recently discussed the possibility of her Black Widow Marvel character Natasha Romanoff returning to the big screen. Speaking on the Today show in November to promote her skincare line The Outset, Johansson said "It would be a miracle,” if her superhero character made a comeback.
“I think it was the end, right? ... She passed," Johansson said as she referred to the moment in Avengers: Endgame when Black Widow — also known as Romanoff — obtains the Soul Stone from Thanos by sacrificing herself to save the life of Jeremy Renner's Clint Barton/Hawkeye.
She added, "It would be a real Marvel miracle. It would be a marvel. But who knows?"
