Elon Musk has third child with Neuralink executive. Here's how many kids he now has.

Elon Musk had a third child with an executive at Neuralink, his brain implant company. Musk and Neuralink Corp. director of special projects, Shivon Zilis, welcomed the baby earlier this year, Bloomberg News reported.

Neuralink didn't immediately respond to a request for comment. In an interview with the New York Post, Musk confirmed the birth of his third child with Zilis, but did not disclose the child's name or sex. 

Musk told the Post that the birth of his latest child was not kept secret. "As for 'secretly fathered,' that is also false," he told the publication. "All our friends and family know. Failure to issue a press release, which would be bizarre, does not mean 'secret.'"
