Elon Musk’s messy split from Canadian musician Grimes continues to make headlines. The latest update, according to documents obtained by Radar Online: The billionaire filed a child custody suit in the fall after she allegedly flew to California with two of their kids “and never returned.” In previous court filings, Grimes offered a different set of facts, claiming that it was Musk who left for Texas with one of their children without receiving her sign-off. She further alleged that Musk “and his security team controlled nearly every aspect” of her life when the two spent time together.
