Tech executive Shivon Zilis has given birth to Tesla CEO Elon Musk’s 14th child, as Musk has confirmed to be the father of his fourth child with Zilis, according to international media reports.
According to different reports, the pair also share twins, Strider and Azure, along with their 12-month-old daughter Arcadia. They announced the arrival of their son, Seldon Lycurgus, on social media yesterday.

“Discussed with Elon and, in light of beautiful Arcadia’s birthday, we felt it was better to also just share directly about our wonderful and incredible son, Seldon Lycurgus,” Zilis wrote on X. “Built like a juggernaut, with a solid heart of gold. Love him so much.”
Elon Musk, who allegedly welcomed his 13th child with author Ashley St. Clair five months ago, responded with a heart emoji. Earlier the same day, Zilis celebrated her daughter Arcadia’s first birthday with a tribute, writing, “Happy 1st birthday, darling Arcadia. Mommy loves you with all her heart.”

Shivon Zilis and Musk first conceived their son Strider and daughter Azure via IVF in 2021 before confirming in June 2024 that they had welcomed their third child. “All our friends and family know,” the SpaceX founder told Page Six at the time. “Failure to issue a press release, which would be bizarre, does not mean ‘secret.'”
On the work front, Zilis, an artificial intelligence specialist who has worked at Musk’s Neuralink, explained why she wanted to have children with the 53-year-old Musk, stating, “He really wants smart people to have kids, so he encouraged me to.”
