Who Is Sergey Brin's Estranged Wife? All About Nicole Shanahan

Sergey Brin and Nicole Shanahan are going their separate ways after three years of marriage.

The Google co-founder filed for a dissolution of marriage from Shanahan, an attorney and philanthropist, back in early January, according to court documents obtained by PEOPLE.

The two first started dating in 2015, the same year Brin finalized his divorce from his first wife Anne Wojcicki, and eventually tied the knot in 2018, as reported by Business Insider. The couple welcomed a daughter later that year.

Most recently, Shanahan has made headlines after the Wall Street Journal reported that she was involved in a "brief affair" with Elon Musk last fall. Both Shanahan and Musk have since denied the affair.

The Tesla founder and father of 10 responded to the WSJ article on Twitter, writing, "This is total bs. Sergey and I are friends and were at a party together last night!" In another post, he wrote, "I've only seen Nicole twice in three years, both times with many other people around. Nothing romantic."

Shanahan's attorney, Bryan Freedman, responded to the report on her behalf, saying in a statement to PEOPLE, "Make no mistake, any suggestion that Nicole [Shanahan] had an affair with Elon Musk is not only an outright lie but also defamatory."
