Elon Musk

Relationships and children

According to The Wall Street Journal, Musk has fathered at least fourteen children, one of whom is deceased; the sources close to Musk suggest that the "true number of Musk's children is much higher than publicly known". He met his first wife, Canadian author Justine Wilson, while attending Queen's University in Ontario, Canada; they married in 2000. In 2002, their first child Nevada Musk died of sudden infant death syndrome at the age of 10 weeks. After his death, the couple used in vitro fertilization (IVF) to continue their family; they had twins in 2004, followed by triplets in 2006. The couple divorced in 2008 and had shared custody of their children.

In 2008, Musk began dating English actress Talulah Riley. They married two years later at Dornoch Cathedral in Scotland. In 2012, the couple divorced, before remarrying the following year. After briefly filing for divorce in 2014, Musk finalized a second divorce from Riley in 2016. Musk then dated Amber Heard for several months in 2017; he had reportedly been "pursuing" her since 2012.

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[d] 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.

On February 14, 2025, Ashley St. Clair, an influencer and author, posted on X claiming to have given birth to Musk's son Romulus five months earlier, which media outlets reported as Musk's supposed thirteenth child.
