In early May, Musk and artist Grimes welcomed their first child. After three years of dating, the two broke up in September. According to Insider, Musk told Page Six that the pair was “semi-separate” but still loved each other and “on fantastic terms.”

Grimes aggressively defends Musk’s wealth, political donations, and treatment of staff on social media when the former couple came under fire. In August of 2018, Grimes was involved in Musk’s battle with the Securities and Exchange Commission over his controversial “funding secured” tweet. They appeared to part up soon after the incident, but they later reconciled.

Musk is the father of six more children from prior marriages.
