Sergey Brin — the Google co-founder who is the seventh richest person in the world with a net worth north of $93 billion — has filed to divorce his wife of four years, according to a report.

Brin, 48, filed divorce papers to end his marriage to Nicole Shanahan, a lawyer and entrepreneur who is in her late 30s, citing “irreconcilable differences,” according to Insider.

Shanahan reportedly started seeing Brin sometime in 2015. The two married in a low-key ceremony on Nov. 7, 2018.

The couple, who have a daughter together, have been separated since Dec. 15, 2021, according to court filings submitted in Santa Clara County, Calif.
