Grimes makes unexpected claim about ex Elon Musk as they balance their co-parenting relationship

Grimes has claimed her ex Elon Musk has done something 'silly' as they juggle co-parenting responsibilities.

The unlikely relationship between the experimental pop singer and the billionaire tech mogul appeared to blossom around 2018.

During the course of their four-year-long relationship, Grimes, real name Claire Boucher, and Musk went on to welcome three children, son, X Æ A-Xii in 2020, daughter, Exa Dark Sideræl in 2021 via surrogate, and another son, Techno Mechanicus, born in 2022.

Not long after, the pair confirmed they separated and entered a rather messy custody battle with court filings in Texas and California.

The 37-year-old 'Genesis' hitmaker claimed the Tesla boss was preventing her from seeing her youngest son. However, their dispute ultimately settled in summer last year, with Grimes revealing the parents share 50/50 custody of the youngsters.

Now, however, the Canadian star has claimed Musk has been playing some unusual games on X, formerly Twitter, the social media platform that he owns.

After a user discovered she no longer follows her ex partner on the platform, Grimes explained it's because the 54-year-old 'blocked' her.

"For context I'm just living my life,” she said in a post on Thursday (December 11). “He followed me then blocked me. I'm not gna be following and unfollowing. My only priority is co parenting, I am not interested in public dramatics."

She added: "This is so silly lol."

Her insight comes as the pair have had quite a rocky few years navigating co-parenting.

In 2023, Grimes filed a petition requesting parental rights for all three of her children, according to online records viewed by PEOPLE.

A year later, in November 2024, she revealed she had postponed making or releasing any new music due to the ongoing custody battle.

"Spent a year locked in battle in a state with terrible mothers rights having my instagram posts and modeling used as reasons I shouldn't have my kids and fighting and detaching from the love if my life as he comes unrecognizable to me, with a fraction of his resources (or iq/strategy experience)," she penned on X.

"All the while I didn't see one of my babies for 5 months," Grimes continued. "And this is only what can be said publicly, since most of my experience these last years should remain behind closed doors."

Then, in January this year, the mom came under some intense backlash after Musk was accused of making a Nazi salute in the Capitol One Arena, Washington.

Grimes stated in part: "I am not him. I will not make a statement every time he does something. I can only send love back into a world that is hurting.

"I choose my children's wellbeing. I promise you it doesn't feel good to be hated all the time for things I don't even know about, cannot predict and cannot control.

"But I also chose this path, I accept it. I make the best of it, and I simply wish happiness and health to all."

Days later, she clarified her position, writing: "If it wasn’t clear – ****I very much denounce Nazi-ism and white supremacy*****."

A month later, she then appeared to criticise the SpaceX CEO for bringing their eldest son, then four years old, to the Oval Office as Musk commandeered the Department of Government Efficiency (DOGE) under the Trump administration.

"He should not be in public like this," the mom shared on X at the time, while in another interview with TIME, she requested people 'stop posting images of my kid everywhere,' adding: "Fame is something you should consent to."
