Elon Musk is a father once again.

The Tesla CEO and his girlfriend, Shivon Zilis, recently welcomed a baby boy, though it’s unclear when. Zilis shared the news in a post on X (formerly Twitter) on Friday, February 28.

“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. Built like a juggernaut, with a solid heart of gold. Love him so much,” Zilis wrote.

Musk commented on the post with a red heart emoji. The announcement has since gone viral with more than three million views, and fans have reacted to the news.

“Wow, another one? Well the baby will be well provided for,” one person wrote. “Beautiful couple. Loved seeing you at the White House together,” someone else said. “You’re a lucky couple! Best wishes,” a third comment read. “I see respect and love. Thank you for sharing with us. You both look gorgeous in your recent trip to the White House. Congratulations to Seldon for having a mother like you,” a fourth X user added.

It’s unclear how long Musk and Zilis have been romantically linked. Their relationship first made headlines in 2022 when court documents obtained by Insider showed that Musk and Zilis had quietly welcomed twins, Strider and Azure, the year prior.

At the time, the couple wanted to change the last names of their babies to Musk, with their middle names including Zilis. The request was granted. Musk and Zilis are also parents to Arcadia, who turned 1 on February 28.

Musk is also a father to three children with ex, Grimes. They share a son named, X Æ A-12, 4, a daughter named Exa Dark Sideræl, 3, and another son named Techno Mechanicus, who is 2.

He has five kids with ex, Justine Wilson, including twins, Griffin and Vivian, born in 2004, and triplets, Kai, Saxon and Damian, born two years later. Their first son, Nevada Alexander, was born in 2002 and died at 10 weeks old.

In February 2025, a woman named Ashley St. Clair came forward claiming that she gave birth to Musk’s 13th child.
