Grimes supports ex Elon Musk's trans daughter after his claim Vivian ...

Grimes has got Vivian’s back.

The singer came to the defense of her ex Elon Musk’s 20-year-old transgender daughter Thursday with a pointed social media post.

“I love and am forever endlessly proud of Vivian,” Grimes, 36, wrote via X.

The artist’s statement came three days after Musk, 53, went viral for claiming his and his ex-wife Justine Wilson’s daughter was “killed by the woke-mind virus.”

The Tesla founder, who used his estranged child’s deadname during a conversation with Dr. Jordan Peterson, alleged he was “essentially tricked into signing documents” for Vivian’s gender reassignment surgery.

“There was a lot of confusion,” Musk said in the Daily Wire interview Monday, recalling being told Vivian “might commit suicide” if she did not undergo the procedure.

Elsewhere in the Q&A, Musk “vowed to destroy the woke-mind virus” and claimed to be “making progress” in that area.

Vivian clapped back Thursday, notably writing her response via Mark Zuckerberg’s Threads platform instead of X, which her dad bought in 2022.

“I look pretty good for a dead bitch,” she wrote.

Vivian went on to dismantle specific “fake” claims Musk made, from her “pick[ing] out clothes” for him at age 4 to being obsessed with musical theater.

She also clarified that she was the one to “disown him,” saying, “He doesn’t know what I was like as a child because he quite simply wasn’t there, and in the little time that he was I was relentlessly harassed for my femininity and queerness.

“As for if I’m not a woman… sure, Jan. Whatever you say. I’m legally recognized as a woman in the state of California and I don’t concern myself with the opinions of those who are below me.”

Musk revealed he and Vivian were estranged in October 2022, four months after she was granted a name and gender change.

“Can’t win them all,” the 12-time dad told the Financial Times. “I have very good relationships with all the others.”

The entrepreneur welcomed Vivian and her twin, Griffin, as well as triplets Saxon, Kai and Damian, 18, while married to his ex-wife Wilson.

The former couple were also the parents of son Nevada, who died at 10 weeks old in 2002.

Additionally, Musk shares three children each with Shivon Zilis and Grimes, whose real name is Claire Elise Boucher.

The songwriter, who dated Musk on and off from 2018 to 2022, gave birth to son X AE A-XII and welcomed daughter Exa via surrogate in 2020 and 2021, respectively.

The duo have not shared details about their third child, Techno.
