Elon Musk allegedly broked 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 two filed for divorce earlier this year, citing “irreconcilable differences,” however, Musk has now denied both the alleged affair and said he is still friends with Brin, claiming the report is based only on “third-party random listen.

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.

 Sources tell the WSJ that Brin and Shanahan were divorced but still living together at the time. The couple’s relationship was reportedly strained due to issues relating to the COVID-19 lockdowns and their three-year-old daughter.
