Singer Grimes has filed a legal petition over parental rights of the three children she shares with Elon Musk.
Court records show that Grimes, whose legal name is Claire Boucher, filed a petition to establish parental relationship last Friday.
Grimes previously accused Mr. Musk of blocking access to one of her sons in a now-deleted social media post.
The 52-year-old Mr. Musk has at least 11 children with three different women.
The details of the petition, filed to the Superior Court of San Francisco are not publicly available.
