Scarlett Johansson is back on the red carpet.

The “Avengers” actress, 36, stepped out at the 2021 American Cinematheque Gala on Thursday — her first public appearance since giving birth to son Cosmo in August — wearing a white Versace suit over a crystal-covered corset.

Johansson linked arms with husband Colin Jost and told “Entertainment Tonight” that she’s been staying home with their newborn as much as possible.

“I feel very fortunate that I’ve been able to take this time to really enjoy the early stages of my motherhood with our son,” she said. “It’s been wonderful. I’m in a ‘baby bliss bubble.’”

Johansson added that her 7-year-old daughter, Rose, whom she shares with ex-husband Romain Dauriac, thinks her baby brother is “cute” but is ultimately too “busy” to care.

Marvel president Kevin Feige presented the Oscar winner with an award at Thursday’s gala — and even teased that she has returned to work on a “top-secret” project with the studio as a producer.

Johansson is the first actor to cross over into a producing role with Marvel, having worked on this year’s “Black Widow” movie — which ultimately ended in a lawsuit against Disney in which she alleged the company had breached her contract by simultaneously releasing the flick in theaters and on streaming platforms.

They have since settled the lawsuit, and Johansson told USA Today that she’s “very fortunate that I was able to stand up for what was right.”
