Scarlett Johansson and Colin Jost got into the holiday spirit on Friday night.

The superstar couple threw a star-studded holiday party for their famous friends.

The Iron Man actress, 39, looked gorgeous in a form-fitting red dress that fell to just above her knees.

She paired the festive frock with sheer black hose and sky-high red heels with an ankle strap and a cozy-looking beige coat.

The Black Widow star and her Saturday Night Live actor and writer husband, 41 – who took a playful jab at his wife on the SNL season finale – hosted the party at the upscale bar The Flatiron Room in New York City.

The busy mom of Rose, nine, who she shares with her ex-husband Romain Dauriac, and son Cosmo, two, with Jost, sat down with Jimmy Fallon on The Tonight Show Starring Jimmy Fallon to talk about preparing for Christmas.

The Lost in Translation star explained that her daughter asked for some very specific gifts for Christmas this year.

‘She does have a list of toys and things, but they’re pretty specific. So she’ll be like, “I want a dress. It’s fluffy on the top. And then on the sides it’s got little sequins,”‘ she said.
