Actress Scarlett Johansson and new boyfriend comedian Colin Jost were pictured sharing a passionate kiss in New York City.

The couple reportedly could not seem to get their hands off each other after the "Saturday Night Live" after-party on early Sunday morning.

Sources who saw the couple told Us Weekly that they looked "very happy together." The onlooker added that the 35-year-old "SNL" host was very protective of the 32-year-old Marvel hero. "He tried blocking her from the photographers and the rain at the same time as they left," said the source.

The new couple reportedly stopped several times to kiss, with Johansson all smiles. "She wrapped herself around him and kissed him. It was like no one else existed in their world ... even in the rain," gushed the onlooker.

Jost and Johansson were first spotted together back in May, also at an "SNL" after-party. Multiple sources then confirmed to Page Six that the two hung out together at 30 Rock for the show's season finale celebrations. They were also seen kissing several times. This was four months after the so-called Black Widow separated from her husband, French journalist Romain Dauriac, with whom she shares her 3-year-old daughter Rose.

Jost first talked about Johansson in an Emmy Awards interview with Entertainment Tonight back in September, where he said work prevented the actress from joining him at the red carpet. "She's pretty cool... It's hard to have a lot of complaints, she's pretty awesome," he said of his rumored girlfriend.

It was back in July when a source close to the duo told E! News that they are "dating and having fun." The insider clarified that the pair are still getting to know each other, but that they are getting on a more "exclusive level."

Despite being spotted together on several occasions, the rumored couple have yet to admit their relationship.
