Scarlett Johansson adoringly gazed at her third husband Colin Jost while attending the American Museum Of Natural History Gala in Manhattan on Thursday.

The 41-year-old SNL co-head writer and the 39-year-old former child star – who began dating in May 2017 after she hosted the NBC sketch show for the fifth time – celebrated three years of wedded bliss last month.

Scarlett and Colin looked thrilled to have a glamorous date night without their two-year-old son Cosmo and her nine-year-old daughter Rose from her second marriage to Romain Dauriac, which ended in September 2017.

Johansson flaunted substantial cleavage in a black silk cocktail dress with matching clutch and pumps as well as a white maxi-coat selected by stylist Kate Young.

Hairstylist David von Cannon coiffed the two-time Oscar nominee’s piecy updo and make-up artist Frankie Boyd applied her bright red pout.

Meanwhile, Jost – who graduated cum laude from Harvard University in 2004 – looked sharp in a classic tuxedo at the black-tie event.

The native New Yorkers were pH๏τobombed by the 14-time Emmy nominee’s colleague, SNL cast member Mikey Day.

Colin currently stars as sad corporate loafer Trent Brockett opposite Wanda Sykes in the Audible Original catfishing comedy Trust Fall, which premiered Thursday.

The podcast production also features current SNL cast member Heidi Gardner as well as Rachel Dratch, Cecily Strong, Jay Pharoah, and Neil Patrick Harris.

Jost – who’s the Weekend Update anchor – is overseeing this Saturday’s episode hosted by five-timer Emma Stone, and featuring musical guest Noah Kahan.

‘It’s definitely an adjustment in the household,’ Scarlett told ET last month of the SAG/AFTRA and WGA strikes finally ending.

‘That [SNL] schedule is so crazy. But it’s always exciting to see those guys. They’re incredible, and we need them now more than ever.’

Johansson has three upcoming films – Josh Cooley’s animated prequel Transformers One, Jason Bateman’s space race drama Project Artemis for Apple TV+, and Kristin Scott Thomas’ feature directorial debut My Mother’s Wedding.
