In 2018, Musk and Canadian musician Grimes said that they were dating. Grimes gave birth to Musk's seventh child in May 2020. In December 2021, Grimes and Musk had a second child together (Musk's tenth child), born via surrogacy. Despite the pregnancy, Musk confirmed reports that the couple were "semi-separated" in September 2021; in an interview with ''Time'' in December 2021, he said he was single. In March 2022, Grimes said of her relationship with Musk: "I would probably refer to him as my boyfriend, but we're very fluid." Later that month, Grimes tweeted that she and Musk had broken up again. In September 2023 it was reported that the pair had had a third child (Musk's eleventh). In October 2023, Grimes sued Musk over parental rights and custody of their eldest.

In July 2022, ''Insider'' published court documents revealing that Musk had had his eighth and ninth children, twins born via IVF with Shivon Zilis, director of operations and special projects at Neuralink, in November 2021. They were born weeks before Musk and Grimes had their second child via surrogacy in December. The news "raise questions about workplace ethics", given that Zilis directly reported to Musk. Zilis's third child together with Musk (his twelfth child) was born in early 2024 via surrogacy. His fourth child with Zilis was born in 2025.
