Their love story is rooted in Saturday Night Live (SNL), where they first crossed paths. While Colin Jost recalls their first meeting in January 2006 when Johansson hosted SNL for the first time and he was a new writer, Johansson's first clear memory of Jost dates to 2010, when he wrote a sketch for her second hosting gig. Despite these early interactions, their romantic relationship didn't blossom until 2017. At that time, Johansson had recently finalized her divorce from Romain Dauriac, and Jost was also single.
Dating rumors began in May 2017 after the SNL season finale, where they were seen sharing a hug on stage and reportedly kissing at the afterparty. Jost publicly confirmed their relationship in September 2017 at the Emmy Awards, expressing his happiness. They made their public debut as a couple at the American Museum of Natural History Gala in November 2017.
