Musk, arguably Trump’s most influential ally and a confidante, ended his speech at one of Monday’s inaugural celebrations by twice using a one-armed gesture that strongly resembled the Roman salute adopted by the Nazis and used regularly by white nationalist groups.

The singer, who uses they/them pronouns, lashed out online after one follower said she planned to cover up her tattoo of Grimes in the outrage, which Tesla mogul Musk, 53, dismissed as “dirty tricks” from haters.

Grimes, Elon Musk's ex, has responded to the backlash of his controversial hand gesture, which is going viral. On Monday, the Tesla CEO took the stage in Washington, DC's Capital One Arena, beginning his speech by saying, "Thank you for making it happen. Thank you," followed by slapping his right hand on his chest and extending it in salute.

Grimes has said she’s “happy to denounce Nazi -ism” after her former partner Elon Musk was accused of giving a “Nazi salute” during an inauguration celebration for Donald Trump.

Elon Musk's former partner Grimes has severed all ties with him after his controversial Nazi-like salute ignited widespread outrage. The ex couple, once hailed as one of the most talked-about duos, is now at the center of a heated debate over Musk's recent actions and Grimes' decision to distance herself publicly.
