One reason was Tesla and SpaceX CEO Elon Musk's brief affair with Nicole Shanahan, wife of Google co-founder Sergey Brin

Which led to Brin and Shanahan filing for divorce earlier this year

The report also stated that the two tech billionaires may have ended their friendship due to Shanahan and Musk's affair

Earlier in 2022, Musk fell on one knee in front of Brin, The Wall Street Journal reported

Brin confirmed the apology but does not speak to Musk on a regular basis, the report added

Brin and Musk are close friends, and Musk has previously said he "regularly hit the search engine founder's house" for several years

During the 2008 financial crisis, Brin provided Musk with approximately $500,000 for Tesla

Musk also presented Brin with one of Tesla's first electric sports cars in 2015

Brin asked his financial advisor to sell his personal investment in Elon Musk's company
