Grimes claims that ex Elon Musk sent a photo of her having a C-section to some of their closest friends and family — including her dad and brothers.
In Musk’s eponymous biography, writer Walter Isaacson — who shadowed the SpaceX CEO for about three years — recalled talking to the “Genesis” performer about the uncomfortable situation.
“He was just clueless about why I’d be upset,” Grimes, 32, told Isaacson, in an excerpt per People.
Elsewhere in the book, Isaacson revealed that the pair secretly welcomed a third child, a son named Techno “Tau” Mechanicus.
While it’s unclear when the little one was born, the pair already share 1-year-old daughter Exa Dark Sideræl — whose nickname is “Y” — and 3-year-old son X Æ A-12, or “X” for short.
The now exes dated on and off from May 2018 until March 2022, but they have remained close ever since.
However, the pair seem to have hit a slight blimp in their co-parenting relationship as Grimes — whose real name is Claire Elise Boucher — took to Twitter last week to shade her ex.
After Isaacson shared a photo of the Tesla founder’s twins — Strider and Azure — with Shivon Zilis, Grimes tweeted back, “Tell Shivon to unblock me and tell Elon to let me see my son or plz respond to my lawyer.
“I have never even been allowed to see a photo of these children until this moment, despite the situation utterly ripping my family apart.”
It’s unclear which one of her sons the “Oblivion” singer was referring to.
Musk, 52, and the Neuralink executive, 37, secretly welcomed their twins in November 2021, yet they waited nearly a year to share the news.
Grimes, who quickly deleted the snarky tweet, took to Twitter a few days later to “de-escalate the narrative” that there was drama between her and Zilis.
“I spoke with Shivon at length finally, which was long overdue. This wasn’t her fault, plz don’t be angry at her!” Grimes started. “We respect each other a lot and we’re excited to become friends and have the kids grow up together.”
She continued, “I truly apologize for responding to Walter like that. As u can imagine, that was a very gut level reaction to a thing that has been very hard for me. Communication about the twins wasn’t handled super well in the past, but I now totally understand what happened and totally forgive the situation.”
While it’s unclear what miscommunication the singer was referring to, she explained that she has nothing but love for Zilis.
“Women are so often pitted against each other. Speaking with Shivon, it’s very evident she’s an amazing human and we both just want what’s best for our kids.”
As for her secret third child with Musk, Grimes noted that her “priority [right now] is keeping my babies out of the public eye.”
Soon after, Zilis responded to Grimes, saying she hopes to spend more time with the musician in the future.
“At the end of the day it all ended up for the best!” Zilis tweeted. “Thank you for taking the time to really connect and understand each other.”
“So glad we had such a wonderful talk, was insanely overdue. You’re a total badass and I respect you very much as well. I can’t wait for kiddo play date and congrats on baby Tau as well!”
Musk is also dad to six children with ex-wife Justine Wilson, who he was married to from 2000 to 2008.
