Grimes is reportedly dating military whistleblower Chelsea Manning—following the Canadian singer’s breakup with Tesla CEO Elon Musk.“They’re getting serious. They U-Hauled it,” a source told the New York Post of the fast-paced nature of their relationship. “They’ve been living together in Austin.” Neither Grimes nor Manning have confirmed the news, but messages back and forth on social media have hinted for a few months that they were romantically linked and a close source claimed that they’re living together. Grimes recently ended her on-again, off-again relationship with Musk, just after the two welcomed their second child together. On Thursday, Grimes tweeted that Musk was her “best friend and the love of [her] life,” but she was more so focused on her work.
