Tesla Inc boss Elon Musk said late on Sunday on Twitter that he and Google co-founder Sergey Brin remain friends and denied a report that he had been involved in an affair with Mr Brin's wife Nicole Shanahan.
Mr Musk's tweets came after a Wall Street Journal report that cited unidentified sources saying he had engaged in a brief affair with Ms Shanahan. The paper said the affair prompted Mr Brin to file for divorce from Ms Shanahan earlier this year and ended the tech billionaires' long friendship.
Dismissing the report, Mr Musk tweeted, "Sergey and I are friends and were at a party together last night! I've only seen Nicole twice in three years, both times with many other people around. Nothing romantic."
Tesla and Google, whose parent company is Alphabet Inc, did not immediately respond to Reuters' requests for comments outside regular business hours.
Reuters wasn't immediately able to reach Mr Brin or Ms Shanahan for comment. A lawyer for Mr Brin declined to comment to the WSJ, and Ms Shanahan didn't respond to requests from the paper for comment.
Mr Brin filed for divorce citing "irreconcilable differences," the Journal said, quoting records it said were filed in Santa Clara County Superior Court. Reuters wasn't able to determine independently whether divorce papers have been filed.
In its report, the WSJ also said Mr Brin instructed his advisers to sell personal investments in Mr Musk's companies after he came to know about the affair. The paper said it wasn't able to determine how large those investments were, nor whether any sales were made.
The Wall Street Journal did not immediately respond to Reuters' request for comment on Mr Musk's denial of the report outside of regular US business hours.
