Kim Petras and Sam Smith win Best Duo at the Grammys.

They are trans– cross all borders.

Singer-songwriters Sam Smith and Kim Petras made music history as the first non-binary and transgender artists to take home Grammys Gold in the Best Pop Duo/Group Performance category.

“I’m the first transgender woman to win this award,” said an emotional Petras, 30, dressed in purple. “I want to thank all of the incredible transgender legends ahead of me who pushed open these doors.”

She went on to thank her mother, her late friend Sophie, LGBTQ+ advocate and pop music icon Madonna, 64.

The trendy hot duo wagged tongues in fiery red outfits as they accepted the award for their chart-topping duet “Unholy” at Sunday’s awards ceremony.

Smith, 30, came out as non-binary in 2019 and changed her pronouns to her/them in September of that year.

Petras, a singer-songwriter from Westphalia, Germany, is transgender. She recently revealed that her cheeky use of religious themes in music is a means of healing trauma, which has been spurred on by pious critics.

“I just had to say from a young age, ‘I’m going to hell.’ That was my childhood experience,” Petras told the Associated Press. “Had I had the chance to be part of a religion, I might have done it. And maybe I would have lived more the way people protesting my concerts want me to live.”

Smith and Petras’ monumental win was preceded by Brazilian singer Liniker, 27, who became the first trans artist to win a Latin Grammy in 2022.

And in 1968, Wendy Carlos, 83, became the first openly transgender woman to win three Grammy Awards for her seminal masterpiece Switched-On Bach.
