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.
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.
