Elon Musk and Grimes have welcomed three children together amidst their on-and-off relationship. The Tesla founder and the singer first linked up in 2018 and welcomed their first child, son X Æ A-Xii, in May 2020. The couple then quietly had two more children, including daughter Exa Dark Sideræl in December 2021 via surrogate, and son Techno Mechanicus in June 2022. Musk is also a father to nine other children, six from his previous marriage and three with an executive at one of his companies.
After the birth of X, Musk spoke to The New York Times in July 2020 about Grimes taking the lead parenting role when the baby was an infant. Now, with three children and multiple breakups behind them, Grimes focuses on co-parenting with Musk amicably, aiming to maintain a positive relationship with her children. She highlighted her dedication to having a strong relationship with her kids, balancing discipline with being their friend.

In October 2023, Grimes filed a petition to establish parental rights for all three children. A year later, in November 2024, she revealed on social media that she refrained from releasing new music due to a custody battle with Musk, which had affected her creatively. Grimes expressed the challenges and emotional toll of the custody battle, addressing the difficulties she faced during that time.
Let’s explore the unique names chosen for Elon Musk and Grimes’ children and their approach to co-parenting. X Æ A-Xii was born in May 2020, with the unusual name carrying personal significance for the couple. Grimes revealed the intricate meanings behind the name, such as the representation of the unknown variable and a nod to their favorite aircraft. The couple later adjusted the name to X Æ A-Xii to comply with California law.
In December 2021, the couple welcomed their daughter, Exa Dark Sideræl, via surrogate. The name Exa Dark Sideræl embodies meanings related to supercomputing, the unknown, and deep space time. Grimes affectionately refers to her daughter as Y, sharing glimpses of her love for techno music and her budding engineering interests. The couple has maintained a private life for their daughter, much like their son X.
The arrival of their third child, Techno Mechanicus, in June 2022 remained shrouded in secrecy until it was disclosed in Walter Isaacson’s biography about Musk. Grimes described Techno, also known as Tau, as a remarkable child with deep eyes and vast knowledge, likening him to a Vulcan. Grimes prioritizes keeping her children out of the public eye, emphasizing the importance of respecting their privacy.
Grimes and Musk’s parenting journey reflects their dedication to nurturing their children’s interests and providing them with a sense of normalcy amidst their high-profile lives. From fostering X’s passion for rockets to embracing Y’s love for techno music and Techno’s enigmatic presence, the couple navigates parenthood with care and consideration. Their commitment to shielding their children from the public eye underscores their focus on family and privacy.
In conclusion, Elon Musk and Grimes’ unique approach to parenting and their children’s distinctive names offer a glimpse into their family dynamics. As they continue to co-parent and care for X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus, the couple prioritizes privacy and respect for their children’s individuality. Their journey showcases a blend of creativity, love, and devotion as they navigate the challenges and joys of raising their family together.
