Washington, March 1 -- Billionaire entrepreneur Elon Musk has welcomed his 14th child, this time with partner Shivon Zilis, as they celebrate the arrival of their fourth child together.

Zilis took to her X account to announce the birth of their fourth child, 'Seldon Lycurgus'. However, she did not reveal when the baby was born.

In her post, she wrote, "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 to her post with a simple red heart emoji.

The two also share twins, Strider and Azure, 3, and daughter Arcadia, 1.
