(Reuters) - Tesla Inc Chief Executive Elon Musk and Shivon Zilis, a top executive at his brain-chip startup Neuralink, had twins in November of 2021, Business Insider reported on Wednesday.
In April, Musk and Zilis filed a petition to change the name of the twins to "have their father's last name" and contain their mother's last name as part of their middle name, the report said, citing court documents.
A month later, a Texas judge approved the petition, the report added.
A court docket summary on the Westlaw legal research service showed a judge signed an "Order Changing the Names Of Multiple Children" on May 11 after the name change petition from Musk and Zilis made on April 25 this year.
The report said, without citing any source, that Zillis has recently been floated as one of the people Musk could tap to run Twitter Inc after his $44 billion deal acquisition.
Zilis, 36, is identified on her LinkedIn profile as director of operations and special projects at Neuralink, which is co-founded and chaired by Musk, 51. She started working at the company in May 2017, the same month she was named a project director in artificial intelligence at Tesla, where she worked until 2019.
She also serves as a board member at artificial-intelligence research firm OpenAI, which was co-founded by Musk, according to her profile on LinkedIn.
The news of the twins' arrival brings Musk's total count of children to nine. Musk shares two children with Canadian singer Grimes, and other five kids with his ex-wife Canadian author Justine Wilson.
Musk and Grimes welcomed their second child via surrogate in December. The billionaire said that he and Grimes were "semi-separated," according to a report by Page Six in September last year.
Musk and Zilis did not immediately respond to Reuters' request for comments.
