Grimes sues Elon Musk over parental rights of their children

Musician Grimes, the former partner of Tesla CEO Elon Musk, is reportedly suing him in a custody battle over their three children. The news comes after Grimes posted a tweet in September 2023 begging Musk to let her see their child.
According to TMZ, Grimes filed a "petition to establish parental relationship" on September 29, 2023. These petitions are used to legally establish the parents of a child to unmarried couples.
It is unclear what specific custody arrangements Grimes is seeking, but the petition suggests that she is seeking custody of her youngest child, Tau, who was born in 2022.
Musk has not yet publicly responded to the lawsuit.
Grimes and Musk began dating in 2018 and had their first child in 2020. They welcomed their second child, in 2021 via surrogate. In September 2023, Musk confirmed that he had a third child with Grimes.
It is unclear when or why Grimes and Musk separated, but they are no longer together.
The custody battle between Grimes and Musk is likely to be complex and high-profile. Both are high-net-worth individuals with busy careers, and they have three young children together.
