Elon Musk, the billionaire tech mogul, has recently welcomed his 14th child, a boy named Seldon Lycurgus, with Neuralink executive Shivon Zilis. This new addition to Musk’s growing family comes just after the couple had three other children together: twins Strider and Azure, and their daughter Arcadia.

Zilis shared the news of his new born son on X (formerly Twitter), saying, “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.”

Musk responded with a simple heart emoji to express his joy.

The announcement follows a row with influencer Ashley St. Clair who claimed that Musk fathered her child. She added that she had kept the information private for her child's safety, but that media interest had made it clear the news would soon be out.

However, Musk, has not publicly responded to St. Clair's allegations.

Elon Musk’s estranged daughter reacts to the news

Musk’s first marriage to Canadian author Justine Wilson resulted in six children, though they tragically lost their first child, Nevada, to Sudden Infant Death Syndrome (SIDS) at just 10 weeks old. Musk's other children with Wilson are twins Griffin and Vivian, and triplets Kai, Saxon, and Damian.

In 2020, Musk and singer Grimes welcomed their son, X Æ A-Xii, followed by two more children—Exa Dark Sideræl and Techno Mechanicus—through surrogacy. Musk also shares twins Strider Sekhar Sirius and Azure Astra Alice, along with Arcadia, with Neuralink executive Shivon Zilis.

After Tesla's founder confirmed that he welcomed his 14th child, his estranged daughter Vivian Wilson, whom he shares with his ex-wife, Cannadian author Justine Wilson, shared a TikTok of her reacting to the news.

In her post, the 21-year-old wrote

"Technically it was through Threads this time though."

Vivian was referencing the previous post she made when St.Clair made the announcement that she bore Musk's 13 child, where she sarcastically said

"wow, if I had a nickel every time I found out I had half-sibling through Reddit. I'd have two nickets, which isn't a lot, but it's weird that it's happening twice right."
