Talking point: Business Insider first reported the news after obtaining legal documents from April in which Musk and Zilis petitioned to give the children their father’s last name. Neither parent has spoken directly about the eight-month-old twins in public, though on Thursday, Musk tweeted: “Doing my best to help the underpopulation crisis.” (He has nine children, including two with Canadian musician Grimes.) Musk and his companies SpaceX and Tesla have been embroiled in sexual harassment scandals. Former SpaceX employees have spoken out about what they described as a culture of sexual harassment, and several Tesla workers have filed sexual harassment lawsuits against the firm. In May, Insider reported that Musk paid a flight attendant US$250,000 to not sue or speak about allegations that the Tesla founder exposed himself and propositioned her for sex. Musk called the accusations “utterly untrue.”
