Last month, Grimes tweeted that she wants to get elf ears — a procedure that would permanently make the tops of her ears pointy.

But she may have trouble finding someone to do it.

After the musician made her intentions known on Twitter — saying she had wanted elf ears her “whole life” and putting out the call for “reputable elf ear modifiers” —  Samppa Von Cyborg was the first person recommended by followers. Grimes concurred: “Ok this is the best person I have found too, maybe I’ll inquire.”

The Spain-based Von Cyborg, however, is lukewarm on the idea.

“I don’t like the idea of a celebrity getting it done, and then all the fans want ear pointing as a result,” Von Cyborg, a body-modification specialist who’s given elf ears to some 500 clients, told The Post. “The [fans] might regret it and it is not reversible. It is not like getting a navel piercing, which became mainstream overnight with the release of the Aerosmith video [for the 1993 song ‘Cryin’,’ in which Alicia Silverstone’s character kicked off a piercing trend].

“Most of my clients are into elves and fantasy and have been wanting the ears since they were kids,” said Von Cyborg. “If Grimes got ear-pointing from me, I would make her sign a document saying she would not tell anyone who did it for her. I don’t want it made into fashion and I want my privacy.”

Von Cyborg told The Post he had not hear from Grimes, and a call to her publicist has not been returned.

The musician also mentioned that she reached out to Los Angeles plastic surgeon Chia Chi Kao, but his receptionist told The Post that the doctor does not do this type of procedure.

While Grimes’ former boyfriend Elon Musk responded to her on Twitter that “the downside of elf ear surgery probably outweighs the upside,” one of Von Cyborg’s clients can’t recommend it enough.

“I’m glad I did it, I’ve always liked the way elf ears look; I’m a fantasy writer and had prosthetic ones for a while,” novelist Holly Black, who had the “pointing” procedure a few years ago, told The Post. “I think they look cool and elongate the cheekbones.”

According to Von Cyborg, the best candidates for elf ears are people whose ears are oversized and/or stick out — what he calls “Dumbo ears.” 

“We have a lot of clients who got bullied at school because of their Dumbo ears. Then they get the ear-pointing done, it completely changes their lives,” the artist said. “Sometimes they see themselves [afterward] and cry. The body part that they hated the most becomes the one that they the love the most.”

And the bigger the ears, the better.

“The more cartilage there is, the more I have to play with,” said Van Cyborg. Other than that, he will reveal very little about the details of the procedure, which, he says, was taught to him by an ear, nose and throat doctor and took five years to develop. “Let’s just say that I use a scalpel to resculpt the ear, make it pointy and stitch everything back together. On the first night there is a little bit of throbbing, but that is it.”

From her own experience, Black concurred.

“My ears were a little sore and I had to sleep with my ear in an ear pillow” — a protective, donut-shaped device.. “I hadn’t thought about my ears before and now I’m a little vain,” said the “Book of Night” author. “I like to show them off. I pull back my hair and love looking at my ears.” 

While tattoos and extreme piercings tend not to age so well, Black has no worries about her work from Von Cyborg: “I think it will be cool to be an old elf in a nursing home.”
