- A new biography of Elon Musk confirms he has a third child with Grimes named Techno Mechanicus.
- Musk and Grimes had previously tried to keep the existence of their third child private.
- Musk has a total 10 children with three different women.
A new biography of Elon Musk confirms that the Tesla CEO had a previously unreported third child with his ex-partner, Canadian musician Grimes.
The child, whose age has not been made public, is named Techno Mechanicus and goes by the nickname, Tau. Journalist Walter Isaacson, whose biography of Musk is set to release next week, is the first to confirm the couple has a third child, according to a New York Times review of the biography. Isaacson was given unprecedented access to Musk over the last two years.
Accounting for Techno Mechanicus, Musk now has 10 known biological kids with three different women.
Musk and Grimes, born Claire Boucher, first announced their relationship in May 2018. Since then, the couple announced the birth of two children. Their first was born in 2020 and named X Æ A-Xii, or X. The couple revealed news of his little sister, Exa Dark Sideræl Musk, who goes by Y, in March.

Musk and Grimes have since split, but the musician has previously said their relationship is “fluid.”
Isaacson’s unreleased biography has also garnered attention for the scoop that the SpaceX CEO interfered with a Ukrainian offensive attack in Crimea by disabling nearby Starlink coverage.
Musk later tweeted that he never turned the satellites off, instead claiming the satellites were never on and that he refused to activate them. Musk said he feared the planned attack would trigger a nuclear response from Russia.
