On July 6, Business Insider reported that the Tesla mogul welcomed twins with Neuralink executive Shivon Zilis last November.The family size revelation comes after Elon and his various companies have faced allegations of sexual impropriety and harassment in recent months.Although the CEO of SpaceX is keeping the details surrounding his twins under wraps,Business Insider published court documents that say the babies were born in Austin, Texas, where Elon currently resides.The report includes a court document from May 2022, which shows Elon and Shivon petitioning for a name-change to make,"The children's last name to be their fathers, and for their mother's last name to be contained in their middle name."While Elon has yet to confirm the rumor, he did seemingly respond to the news with a tweet, saying,"Doing my best to help the underpopulation crisis. A collapsing birth rate is the biggest danger civilization faces by far."In April, it was revealed that Elon had a second child who was born by a surrogate in late 2021 with former partner and singer Grimes.Elon is now the father to nine known children.
