This is the fourth kid that Elon Musk and Shivon Zilis have welcomed into their family together.
In a post that was published on X on Friday, February 28, Zilis made the revelation, stating that she and Musk, who is 53 years old, are the parents of a second boy named Seldon Lycurgus. She did not disclose the date with which Seldon was born.
After having a conversation with Elon, we came to the conclusion that it would be more appropriate to also talk directly about our lovely and outstanding son Seldon Lycurgus. This was in light of the fact that Arcadia’s birthday was approaching. Built like a juggernaut, with a heart of gold that is strong and unwavering. I have an immense amount of affection for him.
To Zilis’s X post, Musk just responded with the word “♥️.”
According to a source who spoke with People exclusively, Musk “really loves Shivon.”
During the month of November 2021, the creator of Tesla and Zilis disclosed that they had discreetly welcomed twins, a male named Strider and a girl named Azure. According to court records that were revealed by Insider in July 2021, the twins were born only a few weeks before to the arrival of a baby girl with the name Exa Dark Siderael, who was delivered to him and the singer Grimes via the use of a surrogate.
Arcadia, the couple’s third child together, was born on February 28, 2024, which was less than three years after the couple had tied the knot. On Friday, February 28, 2025, she commemorated the first birthday of her daughter by posting an X on her Facebook page. I hope you have a wonderful first birthday, Arcadia. With all her heart, Mommy loves you 💞,” she said in her letter.

Almost two years after Musk and Zilis received their twins, Grimes wrote on X in September 2023, after tweeting and deleting about the mixed family dynamics, indicating that she and Zilis had connected. This was after she had tweeted about the blended family dynamics. She said that they had reached a consensus over the terms and circumstances under which they had each individually welcomed children with Musk, which occurred several weeks apart.
When asked about it on X, Zilis said, “At the end of the day, everything turned out for the best! I am grateful that you have made the effort to really connect with one another and comprehend one another. So happy that we were able to have such a lovely conversation; it was well overdue. You are an absolute badass, and I have a great deal of respect for you as well. Greetings, and congratulations on the arrival of baby Tau! I can’t wait for the youngster play date!
Grimes and Musk are parents to three children: a boy named X Æ A-12, who is four years old, a girl named Exa Dark Siderael, who is three years old, and a son named Techno Mechanicus nicknamed Tau, who is two years old.
The novelist Ashley St. Clair made the statement on Friday, February 14 X that she and Musk welcomed his thirteenth kid, a boy called R.S.C., five months ago. The news of Musk’s fourteenth child followed the announcement that she made.
Five months ago, I became a mother to a brand new baby who entered the world. Musk is the father of the child. In the past, I have refrained from disclosing this information in order to safeguard the privacy and safety of our kid; nevertheless, in recent days, it has been abundantly evident that the tabloid media wants to do so, regardless of the damage that it will ultimately create,” she said.
In a statement that was published on X on Saturday, February 15, the representative for St. Clair, Brian Glicklich, said, “Ashley and Elon have been privately working towards the creation of an agreement about raising their child for some time.”
“We are waiting for Elon to publicly acknowledge his parental role with Ashley, to end unwarranted speculation,” he said in conclusion.
On Friday, February 28, a court issued an order requiring Musk to attend at a hearing scheduled on May 29 about R.S.C.’s custody.

In 2002, Musk became a father for the first time when his ex-wife, Justine Wilson, gave birth to their son Nevada Alexander. Unfortunately, Nevada Alexander passed away when he was only ten weeks old. Five additional children were born to the couple: twins Vivian and Griffin, who are now 20 years old, and triplets Kai, Saxon, and Damian, who are now 19 years old.
