Grimes is weighing in on her ex Elon Musk’s controversial comments.

After the Tesla CEO criticized his daughter Vivian Jenna Wilson for coming out as transgender and seeking gender-affirming treatment, Grimes—with whom he shares children X Æ A-Xii, Exa Dark Sideræl and Techno Mechanicus—is standing by Vivian’s side.

As she wrote on X, formerly Twitter, July 25, “I love and am forever endlessly proud of Vivian.”

Grimes’ comment comes after Elon said he felt Vivian—whom he shares with ex-wife Justine Wilson in addition to late son Nevada Alexander Musk, Vivian’s twin brother Griffin Musk, and 16-year-old triplets Kai Musk, Saxon Musk and Damian Musk—had been “killed” in his eyes by “the woke mind virus” for her decision to seek gender-affirming medical care.

“I was essentially tricked into signing documents,” Elon told Daily Wire in the interview published July 23. “This was really before I had any understanding of what was going on, and we had COVID going on, so there was a lot of confusion.”
