Colin Jost: Biography, Net Worth, Health, and Family

Scarlett Johansson holds her own in Hollywood blockbusters, but the man trading jokes with her at home has a story beyond his famous spouse. Colin Jost is a longtime *SNL* writer and Weekend Update anchor, and this biography sorts fact from rumor around his health, finances, and family.

Occupation: Comedian, writer, actor ·

How many kids do Scarlett Johansson and Colin Jost have?

The couple have one child together: a son named Cosmo, born in August 2021 (Biography.com). Scarlett Johansson also has a daughter, Rose, from her previous marriage to French journalist Romain Dauriac, making Jost a stepfather as well (Harper’s Bazaar).

That adds up to a household of four: two children, but only Cosmo is Jost’s biological child. Rose, born in 2014, lives with shared custody between Johansson and Dauriac (Harper’s Bazaar).

What is the age difference between Scarlett Johansson and Colin Jost?

Scarlett Johansson was born November 22, 1984, making her about 1 year and 5 months older than Jost (IMDb Biography). That puts her at 36 when she gave birth to Cosmo.

Who has custody of Scarlett Johansson’s daughter?

Custody of Rose is shared with Romain Dauriac. The pair divorced in 2017 citing irreconcilable differences (Harper’s Bazaar).

The implication: Jost stepped into a ready-made family dynamic. He’s not just a first-time dad — he’s a stepdad too, which adds a layer of responsibility that doesn’t show up in a typical celebrity bio.

What health issues did Colin Jost have?

In his 2020 memoir A Very Punchable Face, Jost revealed he has been diagnosed with hidradenitis suppurativa (HS), a chronic inflammatory skin condition that causes painful lumps under the skin (Harper’s Bazaar). He underwent surgery for the condition later in 2020.

Some sources claim Jost also developed mal de débarquement syndrome (MdDS), a rare neurological disorder that creates a persistent sensation of rocking or swaying, reportedly diagnosed in 2023 (Canada Scene). But that claim comes from a single lower-tier source, so it hasn’t been corroborated by primary medical or entertainment-industry reporting.

The catch: HS is confirmed by Jost’s own words in his book. The MdDS claim remains unverified and should be treated as rumor until a tier-1 or tier-2 source confirms it.

How many marriages has Colin Jost had?

Colin Jost has been married exactly once — to Scarlett Johansson (October 2020) (IMDb Biography). He had no previous marriages (Harper’s Bazaar).

Johansson, however, has been married twice before. She wed Ryan Reynolds in 2008 (divorced 2011) and Romain Dauriac in 2014 (divorced 2017). Both ended for different reasons: conflicting schedules with Reynolds, and irreconcilable differences with Dauriac (Harper’s Bazaar).

What this means: Jost entered a marriage with someone who already had a public divorce history. His own marital status — clean slate — likely played a role in the couple’s ability to build a blended family without overlapping custody from his side.

Who is richer, Scarlett Johansson or Colin Jost?

Scarlett Johansson’s net worth is estimated at $165 million (Celebrity Net Worth). Colin Jost’s net worth sits at an estimated $10 million from the same source, though a 2026 report from Social Life Magazine pegged it slightly higher at $12 million (Social Life Magazine).

The gap is enormous: about 15× difference. Johansson’s earnings come from her Marvel paychecks, endorsement deals, and production credits. Jost’s income flows from *SNL* salary, writing residuals, and hosting gigs.

The trade-off: financial asymmetry in a celebrity marriage isn’t unusual, but it flips the typical gender ratio. Johansson is the primary earner by a wide margin, which puts Jost in a position where his comedy career is more about creative fulfillment than income parity.

Where do Colin Jost and Scarlett Johansson live?

The couple primarily reside in a townhouse in the West Village, New York City. They also own a home in Los Angeles for work purposes (Harper’s Bazaar).
