At the age of 53, Elon Musk has welcomed his 14th child, his fourth with Shivon Zilis.
Through 'X', Zilis made the announcement, writing that they have become parents of a second son, Seldon Lycurgus.
Her post, with its own dose of weirdness and without specifying when their son was born, said:
"We discussed it with Elon and, with [their daughter] Arcadia's [beautiful] birthday approaching, we thought it best to also share [the news of the birth of] our wonderful and extraordinary son Seldon Lycurgus. Built like a destructive force, with a strong heart of gold. I love him so much."
Musk responded to the post with a heart emoji.
In November 2021, Zilis and the Tesla founder - who has been elevated to the status of senior advisor to the president of the United States since Donald Trump took office for his second term - shared that they had "secretly" given birth to twins: a boy named "Strider" and a girl named "Azure".

According to news reports, the twins were born just weeks before Musk and musician Grimes welcomed their daughter 'Exa Dark Sider l' via surrogate mother.
On February 28, 2024, Zilis and Musk gave birth to their third child together, a daughter whom they named 'Arcadia'.
Sources confirm that Musk and Zilis are really close and that he loves her very much.

Meanwhile, Grimes and Musk have three children together: son X A-12, daughter Exa Dark Sider l, and son Techno Mechanicus aka 'Tau'.
On February 15, 2025, Musk's current partner announced on X that she had given birth to Musk's 13th child, a boy named "RSC".

In 2002, Musk became a father for the first time, when his ex-wife Justine Wilson gave birth to their son Nevada Alexander. However, the baby died at just 10 weeks old. The couple welcomed five more children: twins Vivian and Griffin and triplets Saxon, Kai and Damian.
