Grimes’ mother shared a public letter to Elon Musk, accusing the Tesla CEO of not allowing the former couple’s three children to go on a family trip to visit their ailing maternal grandmother.

Grimes‘ mother is accusing Elon Musk of preventing his and her daughter’s three children from being able to travel to see their ailing maternal grandmother.

Sandy Garossino, a Canadian journalist, published a letter to the Tesla CEO on his social media platform X July 27. She made her comments amid an ongoing custody battle between her daughter and the billionaire, who share kids X Æ A-Xii, 4, Exa Dark Sideræl, 2-and-a-half, and Techno Mechanicus, 2.

“Dear Elon @elonmusk. It was nice seeing you on Father’s Day. I hope you got the card that I helped X make,” Grimes’ mom began. “He was so proud of it.”

She continued, “I’m writing here as the only way I have to reach you. As you know, my 93 year old mother is now at end-of-life palliative care. She yearns to see and hold Claire’s children one last time. Especially the youngest, whom she has not yet met.”

Meanwhile, following her mother’s public plea, Grimes has received public support from Musk’s estranged daughter Vivian Jenna Wilson, who he shares with ex-wife Justine Wilson.

The 20-year-old reposted Garossino’s X comments on the Meta-owned Threads app and accused her father of keeping his and Grimes’ children, “away from their mother during the most important developmental period in a child’s life.”

She alleged that the kids “are stuck in a house thousands of miles away without their mother,” adding, “This is not the first time this has happened and if nothing changes, likely not the last.”

Musk and Grimes have not commented on Vivian’s remarks, which she made days after the musician expressed support for her amid her transgender journey and a public feud with her dad, who said in a recent interview that his “son” was “dead, killed by the woke mind virus.”

“Last time I checked,” she wrote on Threads July 22. “I am, indeed, not dead.”

Musk, a father of 12, has not responded to Garossino or Vivian’s remarks. E! News has reached out to the X CEO and Grimes for comment and has not heard back.
