Shivon Zilis, the mother of four of Elon Musk’s children and a senior executive at his company Neuralink, publicly announced their abrupt breakup on X on Friday. She said the relationship ended "with no warning" just one week after they were still exchanging "I love you" messages, noting: "It’s hard to go from in love to let go in a week with no warning, but that’s just how it is sometimes."
The 40-year-old and former biotechology executive posted in response to an automated account flagging that Musk had unfollowed her on X, which she described as the final confirmation of the split.
Zilis revealed a screenshot of a September 24 text exchange where she wrote, "It was really wonderful to see you for breakfast. Love you very much 💕,"and Musk replied, "Love you too." He added he hadn’t realized he could bring a plus-one to a White House state dinner for Chinese President Xi Jinping or he would have invited her.
Despite the suddenness, Zilis expressed no bitterness. She wrote, "I’ve loved him more than life itself... there is a lot of loss, but luckily we created four beautiful little loves of my life." She described their home as Musk’s "safe space" and "counterbalancing place of safety" away from his "militant existence."
"I do hope and pray he and I can be great friends and coparents," she wrote, and ended with, "God speed, Elon, the world is lucky to have you."
Three days after the White House state dinner for Xi Jinping, where Musk attended without Zilis, she cryptically posted "New day, new life" on X without context.
Their relationship began around 2016 when Zilis, then working at OpenAI, had a "one-off" encounter with Musk. It evolved romantically after she decided to have children as a single mother and Musk agreed to act as a platonic sperm donor.
They share four children via IVF: twins Strider and Azure (born Nov 2021), Arcadia (age 2), and Seldon (born Feb 2025).
Zilis worked at Tesla (2017–2019), advised OpenAI (2016–2023), and now serves as Director of Operations and Special Projects at Neuralink.
