Nicole Shanahan, wife of Google co-founder Sergey Brin, denies she had an affair with Elon Musk.

On July 27, her lawyer released a statement in response to a Wall Street Journal report that cited unidentified sources as saying she had engaged in a brief affair with the Tesla CEO last December while separated from Brin, a claim Musk himself also recently denied.

Shanahan’s attorney, Bryan FreedmanNBC News: “Make no mistake. Any suggestion that Nicole was having an affair with Elon Musk, is not just a lie, but defamatory.”

According to its July 24 Report, WSJ cited its sources as saying that the alleged affair prompted Brin to file for divorce from Shanahan earlier this year and also ended the tech billionaires’ long friendship. In response to the article, Musk tweeted, “This is total bs. Sergey is a friend of mine and we were there last night at a party. Nicole has been to my house twice, but both occasions were with several other people. It’s not romantic.”
