Just call her the Duchess of Darkness.

Elvira had a cheeky response to Meghan Markle after the As Ever founder recounted a traumatizing time she dyed her hair an unflattering shade.

Markle, 43, revealed that, during the height of the COVID-19 pandemic, she turned to box hair dye for a touch-up — with disastrous results.

Meghan Markle mentioned in a recent podcast episode that she wanted her hair to look like the image on a hair dye box.

She described the color as a very dark and almost like the iconic character Elvira’s black hair.

Cassandra Peterson, who played the horror character, apparently saw the clip — and offered her services to the royal.

To achieve the desired look, Markle reached out to her wedding-day hairstylist Serge Normant who connected her with hair expert Kadi Lee, a guest on the podcast.

One fan commented, “She wishes she looked like Elvira” while another said, “She should be so lucky.”

A third, however, thought of a good solution. “I hope she sees this and invites you on her show to do Halloween special! 👏🏽 🦇 Love you both!,” they said.

Elvira has a history of getting into it with celebs; in 2024, she called out Ariana Grande as the worst interaction she’s had, claiming the “We Can’t Be Friends” singer snubbed her at a meet and greet.

Meanwhile, the queen of scream had some issues when Kylie Jenner dressed as her for Halloween. “I didn’t get a heads up that Kylie was doing the costume, but she did the costume justice and it was very flattering,” Elvira said of the transformation. “It would have been even more flattering if she tagged me.”
