'Avengers: Infinity War' premiere: Colin Jost and Scarlett Johansson can't take their eyes off each other

Ah, newly-public love!

Although Colin Jost and Scarlett Johansson have been hot and heavy for nearly a year -- their romance reportedly sparked during Scarlett's appearance on the 2017 "SNL" season finale -- it wasn't until Monday night that the two made it red carpet official.

Colin was by Scarlett's side all night at the star-studded premiere of "Avengers: Infinity War," where the two gazed lovingly at each other as the cameras snapped away. They even shared a brief kiss not far from the paparazzi.

We're used to seeing Colin in a sharp suit behind the "Weekend Update" desk, but Scarlett showed off a bolder look, rocking a head-turning combination of metallic beading, a brunette pixie cut and her very large back tattoo. 

"I'm just excited to share this experience with him because I'm so excited to see the film," Scarlett told ET. "I haven't seen it before!"

Scarlett shares the "Avengers" screen with countless other stars -- Robert Downey Jr., Gwyneth Paltrow, Benedict Cumberbatch, Chris Pratt and (literally) dozens more. Take a look the gallery below.
