Scarlett Johansson and her boyfriend Colin Jost attended the American Museum of Natural History’s 2017 Gala.

SCARLETT JOHANSSON & COLIN JOST MAKE FIRST PUBLIC APPEARANCE

This marks Johansson, 32, and Jost’s, 35, first public event as a couple. The Avengers: Infinity War actress and Saturday Night Live star walked the red carpet separately, but reconvened for photos inside.

Johansson wore a strapless red dress by Yves Saint Laurent. The silky gown featured buttons down the front and large faux pockets at the waist. Johansson paired the dress with a red clutch and red metallic sandals. Jost opted for a classic black tuxedo and matching bowtie.

The unlikely pair were first linked together in May when they were spotted kissing at the SNL season finale afterparty. In September, Jost opened up a bit about the relationship. “She’s pretty cool,” he said. “It’s hard to have a lot of complaints, she’s pretty awesome. I’m very happy. I feel very lucky.”

Also in September, Johansson and ex-husband Romain Dauriac finalized their divorce and settled their custody dispute over their daughter, 3-year-old Rose Dorothy.
