In April, Mr Musk and Ms 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. It also said Ms Zilis has recently been floated as one of the people Mr Musk could tap to run Twitter Inc after his $44 billion deal acquisition. Ms Zilis, 36, is identified on her LinkedIn profile as director of operations and special projects at Neuralink, which is co-founded and chaired by Mr 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 Mr Musk, according to her profile on LinkedIn. The news of the twins’ arrival brings Mr Musk’s total count of children to nine. Mr Musk shares two children with Canadian singer Grimes, and other five kids with his ex-wife, Canadian author Justine Wilson.
