Elon Musk confirmed that he and musician Grimes have a third child, a baby boy, named Tau Techno Mechanicus.
Musk confirmed the news via a tweet, in response to a post by entertainment news account Pop Base.
The ex couple's child joins siblings X Æ A-Xii and Exa Dark Sideræl Musk, both of whom have similarly unique names.
Grimes has yet to comment publicly on the birth of Tau, but it's clear that she and Musk are keeping with their unconventional naming traditions.
Fans are already wondering what the inspiration might be behind the name Techno Mechanicus.
