Scarlett Johansson is balancing her Hollywood career with family life alongside her husband, comedian and Saturday Night Live star Colin Jost, and her two children, Rose Dorothy and Cosmo. The actress, who recently attended the London premiere of her animated science-fiction film Ray Gunn, has maintained a relatively private home life despite her international fame.

Johansson, 41, has been married to Jost since October 2020. The couple welcomed their son, Cosmo, in August 2021, while Johansson also shares her daughter, Rose, with her former husband, French journalist Romain Dauriac.

Her family includes her parents, Karsten Johansson and Melanie Sloan, as well as several siblings, including her twin brother, Hunter Johansson. Although Johansson has spoken about motherhood in interviews, she has generally avoided exposing her children to public attention.

Jost was born on June 29, 1982, in Staten Island, New York. He graduated from Harvard University and joined the writing staff of Saturday Night Live in 2005.

He later became a co-anchor of the show’s Weekend Update segment alongside Michael Che.

Johansson and Jost first met through Saturday Night Live, where the actress has appeared multiple times as a host and guest.

Their romantic relationship became public in 2017. They announced their engagement in May 2019 after approximately two years of dating.

The couple married in October 2020 in a private ceremony attended by close family members and friends.

Jost confirmed their son’s arrival in a social media announcement shortly after his birth.

He wrote, “Ok ok we had a baby. His name is Cosmo. We love him very much.”

Johansson has occasionally discussed her experiences raising children of different ages.

She has also spoken about the challenges of balancing parenting responsibilities with a career that frequently requires travel, long production schedules and promotional appearances.
