Elon Musk sued by ex Grimes over their 3 children

Elon Musk is being sued by ex Grimes over parental rights of their three children.

Grimes filed a “petition to establish parental relationship” on Sept. 29 in a California court, according to court records obtained by Page Six on Tuesday.

The request asks the court to identify the legal parents of a child when they are not married.

The billionaire, 52, and “Oblivion” singer, 35, are parents of three children. Their first son, X Æ A-Xii, arrived in May 2020. In December 2021, they quietly welcomed daughter Exa Dark Sideræl via surrogate.

It was only confirmed in September that the pair secretly had a third child, a boy named Techno Mechanicus, whom they call Tau. The news was revealed in journalist Walter Isaacson’s “Elon Musk” biography.

Isaacson also revealed how Musk initially wooed Grimes with a high-speed Autopilot ride — while closing his eyes. She also gave him a box of animal bones she had collected and they listened to an hour of history podcasts and audiobooks before going to bed.

Musk and Grimes, real name Claire Boucher, dated on and off from 2018 until their official split in September 2021.

Overall, Musk is a father to 11 children with three different women.

Musk and his ex-wife, Canadian author Justine Wilson, welcomed son Nevada Alexander Musk in 2002. Nevada died of sudden infant death syndrome, or SIDS, at only 10 weeks. They went on to use IVF to welcome Griffin and Vivian Musk, who are now 18, and triplet sons Kai, Saxon and Damian, who are now 16.

In November 2021, Musk also welcomed twins with Neuralink director of operations and special projects Shivon Zilis.
