Claire Boucher, the Canadian singer popularly known as Grimes, has sued the billionaire Elon Musk regarding the parental rights of their three children.
In documents obtained by Page Six on Tuesday, Boucher filed a “petition to establish parental relationship” in a California court on September 29. This type of petition is typically used to request a court declaration of the legal parentage of children when their parents are not married.
While the notice of the filing is public, the actual contents of the documents remain sealed.
This lawsuit follows Grimes’ recent public plea to Elon Musk, asking him to allow her to see their third child, whose arrival was kept secret.
In now-deleted tweets, Grimes responded to a post by Walter Isaacson, the author of Musk’s biography, which featured pictures of twin children shared by Musk and Neuralink executive Shivon Zilis.
“Tell Shivon to unblock me and tell Elon to let me see my son or plz respond to my lawyer. I have never even been allowed to see a photo of these children until this moment, despite the situation utterly ripping my family apart,” she wrote in the tweet.
Grimes and Musk had an on-and-off relationship from 2018 to 2021. They welcomed their first child, X, in 2020 and secretly had another child, Exa, through surrogacy in 2021.
The biography of Elon Musk, published in September 2023, revealed that the singer and tech mogul had secretly welcomed yet another son, Techno Mechanicus, although the year of his birth was not disclosed in the biography.
