Congratulations are apparently in order for Elon Musk: The Tesla chief executive had twins in November with Shivon Zilis, a top executive at his company Neuralink. The news of the twins’ arrival, first reported Wednesday by Insider, brings Musk’s total brood count to nine.
Court filings obtained by the outlet showed that Musk and Zilis filed a petition to change their children’s names to “have their father’s last name and contain their mother’s last name as part of their middle name” in April. One month later, a Texas judge approved the petition.
The twins were reportedly born just “weeks” before the SpaceX founder and musician Grimes had a baby daughter via surrogate. The girl is the couple’s second child. Her existence was also kept secret until March this year, when a Vanity Fair reporter sent to profile Grimes heard the “lone cry” of a baby upstairs.
