The couple’s growing family now includes twins Strider and Azure, born in November 2021, and daughter Arcadia, who arrived on February 28, 2024. Their family timeline intersects with Musk’s other family developments, as the twins’ arrival preceded the birth of his daughter Exa Dark Sideræl, whom he welcomed via surrogate with musician Grimes.
The relationship dynamics between Musk’s co-parents made headlines in September 2023, when Grimes addressed the situation on X. She discussed reaching an amicable understanding with Zilis regarding their shared connection to Musk and their children. Zilis responded warmly to Grimes’ message, expressing mutual respect and enthusiasm about future interactions between their children.

Recent developments in Musk’s personal life have drawn public attention, particularly after influencer Ashley St. Clair announced on Valentine’s Day that she had given birth to Musk’s thirteenth child five months earlier. Her representative later disclosed that private negotiations regarding child-rearing arrangements were ongoing, urging Musk to acknowledge his paternal responsibilities publicly. A judge has scheduled a custody hearing for May 29 regarding their son.
Musk’s path to fatherhood began in 2002 with his first wife, Justine Wilson. Their first child, Nevada Alexander, tragically died at ten weeks old. The couple later had twins Vivian and Griffin, now 20, followed by triplets Kai, Saxon, and Damian, who are currently 19.
