Canadian musician and artist Claire Boucher has filed a lawsuit against Elon Musk over the parental rights of her three children, including their youngest, Tau. The lawsuit, which remains under seal, is reportedly centered around their youngest child, after Grimes claimed Musk wouldn't allow her to visit one of their children.

Elon Musk, 52, and Grimes, 35, share a unique family story. Their journey into parenthood began with the birth of their son, X AE A-12. Subsequently, in 2021, they welcomed a daughter via surrogate, naming her Exa Dark Siderael Musk. The couple expanded their family once again with the birth of their third child, a son named Techno Mechanicus.

Grimes filed a petition in San Francisco Superior Court to establish a parental relationship, raising questions about access to one of their children. The petition seeks the court's intervention in identifying legal parentage when unmarried couples face disputes over custody and visitation rights.

Elon Musk and Grimes had a relationship marked by its on-again, off-again nature. Their romantic involvement began in 2018 and endured until their official separation in September 2021. Despite the challenges posed by their high-profile careers and public attention, their bond has resulted in a unique family structure.

Journalist Walter Isaacson's biography of Elon Musk shed light on their relationship's hidden chapters. Notably, it revealed the birth of their third child, which had remained undisclosed until recently. Isaacson's book also unveiled a quirky facet of Musk's courtship—he wooed Grimes with a high-speed Tesla Autopilot ride.

In a separate interview with Wired, Grimes described her relationship with Elon Musk as "the best internship ever." She praised Musk as a "great general" and explained his propensity for engaging in various social issues. She also emphasized that their children would have a distinctive upbringing, given Musk's unique status as a public figure.

Elon Musk's family has grown to 11 children, starting with his firstborn, Nevada Alexander Musk, who died of SIDS at just 10 weeks old. After his death, Musk and Justine started in vitro fertilization, resulting in twins, triplets, son X AE A-X II, and twins in November 2021.

The legal battle between Grimes and Elon Musk adds a new chapter to their already complex story. It raises questions about parental rights, custody, and the intricacies of modern family dynamics. As the case unfolds, the world watches closely, recognizing that even in the lives of billionaires and celebrities, the complexities of family and relationships are universal and subject to legal scrutiny.
