Grimes has taken to Instagram to show off her unusual and painful-looking "alien scars" back tattoo.
Sharing a picture of the new inking with her 1.7 million followers, the singer showed off the elaborate, scar-colored tattoo with a full picture of her back.
It was captioned: "Full back in white ink by @tweakt w sum help from the alien computer brain of @nusi_quero
"Don't have a good pic cuz it hurts too much and I need to sleep haha, and it’'l be red for a few wks , but gna be beautiful alien scars [sic]
"Hope everyone's having a good day."
The unusual tattoo did not go unnoticed on the social media website, and fans of Elon Musk's girlfriend were quick to praise the tattoo for looking so cool – but also comment on just how painful it appeared to be.
One Instagram user wrote: "This looks painful to get."
A second added: "Looks like something a Lazer printer would draw."
A third compared the tattoo to spaghetti.
Meanwhile, a fourth joked: "I fell into a rose bush once too..."
However, while Grimes' new tattoo might not be to everyone's taste, not all Instagram users were so critical.
A fan remarked alongside a heart-eyes emoji: "It looks like some cool scars, makes me want to get something similar."
A second simply praised the tattoo for being so unique.
News of Grimes' new tattoo comes after she and Elon Musk welcomed their first child last year and caused a storm with their equally unusual choice of name.
Grimes explained the meaning of the baby's name on Twitter.
However, in May of last year, the singer revealed that she had to change her son's name because of Californian laws and confirmed it to an Instagram follower.
"Did you change the baby name because of Californian laws? What is the baby's new name?" questioned an Instagram user.
Grimes replied: "X Æ A-Xii".
It is believed that the baby's name is pronounced "X Ash Archangel", with one of Grimes' followers adding: "Nice! Just removed the numbers to conform to California law."
