AceShowbiz - Genderqueer singer King Princess has slammed J.K. Rowling for controversial tweets on sex and gender many have deemed "transphobic."

The "Harry Potter" author hit headlines over the weekend (June 06-07), after tweeting, "If sex isn't real, there's no same-sex attraction. If sex isn't real, the lived reality of women globally is erased."

"I know and love trans people, but erasing the concept of sex removes the ability of many to meaningfully discuss their lives. It isn't hate to speak the truth."

Her intervention sparked fury from LGBTQ+ campaigners and even prompted "Harry Potter" star Daniel Radcliffe to condemn Rowling, with the "Pieces of Us" hitmaker, real name Mikaela Straus taking the writer's comments personally.

"I am not the person you will find calling out people on the internet, but that being said this one is personal," she (her preferred pronoun), captioned a post featuring a black square on Instagram. "JK Rowling ...why I find your comments so disconcerting, damn there are so many reasons."

Explaining her anger, she continued, "First of all, I don't think especially now, that you realize the accidental queer haven you created in your books for so many kids within the LGBT spectrum. Right now you are telling countless trans/femme kids that they basically didn't deserve to be a part of that Utopia. That you pretty much negate the presence of their identities in this world."

Accusing the author of wrongly claiming victimhood, she raged, "You feel like your womanhood is attacked by a movement towards trans equality? What does this AT ALL have to do with you and your womanhood and why do you feel so angry? Are you scared that the inclusion of trans femme people somehow erases you?"

She went on to criticize her for, "refusing to listen to a group of people are being murdered, beaten, and left unprotected by the law everyday."

Other stars who have criticized Rowling for her remarks include, Halsey, Hozier and Sarah Paulson.
