The cute couple looked flawlessly classy as they attended the American Museum of Natural History Gala together on Thursday.
Months after striking up their rumored romance, Scarlett Johansson and Colin Jost are stepping out together.
The Avengers star and the Saturday Night Live castmember were all smiles as they posed for pics at their first red carpet event together while attending the star-studded American Museum of Natural History Gala in New York City on Thursday.
The cute couple dressed to the nines for the black tie affair. Jost, 35, looked flawlessly dapper in a traditional black tuxedo while Johansson, 33, stunned in a shimmering, curve-hugging crimson gown.
Jost -- who has been a writer on Saturday Night Live for over 12 years and has been one of the show's "Weekend Update" anchors since 2014 -- met Johansson when she hosted the long-running sketch comedy series for the first time in 2006.
The pair were first romantically linked in May, when they were spotted packing on the PDA at the SNL after-party following the season 42 finale. Johansson hosted an episode of the show earlier in the season.
Their after-party makeout came two months after the Rough Night actress filed for divorce from ex-husband Romain Dauriac -- with whom she shares a 3-year-old daughter, Rose. The divorce was finalized in September.
ET caught up with Jost at the 2017 Emmy Awards, where he had nothing but praise and adoration for his rumored ladylove.
"She's wonderful. She's working, so otherwise, she'd be here," the 35-year-old writer revealed. "She's pretty cool... It's hard to have a lot of complaints, she's pretty awesome."
Jost opened up about meeting Johansson in 2006 when he was still a freshman writer on the show, sharing, "We've kind of known each other since then...she's the best."
