An Unconventional Relationship From the Start
Musk and Zilis have had an unusual dynamic for years. Biographer Walter Isaacson once described her more as Musk’s intellectual companion than a traditional romantic partner. The two have been connected since at least 2021, when they quietly welcomed twins, Strider and Azure, through IVF. They went on to have a daughter, Arcadia, in 2024, followed by a son, Seldon Lycurgus, in 2025.
