Elon Musk allegedly fractured an old friendship with Google co-founder  Sergey Brin after having an affair with his wife, Nicole Shanahan, according to a report from the Wall Street Journal.

Sources familiar with the situation told the WSJ that the couple filed for divorce earlier this year, citing “irreconcilable differences.”

Musk and Shanahan’s affair allegedly occurred at the high-profile Art  Basel event in Miami following Musk’s split with then-girlfriend Claire  Boucher, also known as Grimes.

Elon Musk reportedly had an affair with Google co-founder Sergey Brin’s wife. Sources tell the WSJ that Brin and Shanahan were separated but still living together at the time.

The couple’s relationship was reportedly strained due to issues related  to the COVID-19 lockdowns and their three-year-old daughter.
