The Tesla CEO denied allegations that he had an affair last fall with Sergey Brin’s wife, Nicole Shanahan, that ended the tech entrepreneurs’ friendship. “Sergey and I are friends and were at a party together last night!” Musk said on Twitter. “I’ve only seen Nicole twice in three years, both times with many other people around. Nothing romantic.” The Wall Street Journal reported that Brin told advisers to sell his personal investments in Musk’s companies. (The Wall Street Journal)

Talking point: The WSJ noted that Brin gave Tesla about US$500,000 during the 2008 financial crisis, which could be worth much more today, though the actual value is unclear. The report comes as Musk faces several high-profile personal and business-related issues. Musk’s quest to buy—or not buy—Twitter has impacted Tesla’s stock over the past few months. The world’s wealthiest person also reportedly fathered children with an executive at Neuralink (Musk’s company that creates human-machine interfaces), and settled a sexual misonduct claim with a flight attendant who said the SpaceX CEO exposed himself and propositioned her for sex.
