Let's Rewatch Sam Smith & Kim Petras' Historic Grammy Performance

The Grammys just got “Unholy!”

Sam Smith and Kim Petras brought the Grammys to its knees with their live performance of “Unholy” tonight after winning an award for the song earlier in the night.

Legendary boundary-breaker Madonna presented the two of them, praising Smith and Petras for being among the new generation of rebels and controversy-makers.

The performance was sinister and sexy, just like the song. Backed by hellish flames and red lights, and dressed in red lace and latex, complete with heels and a BDSM collar, Smith swayed back and forth in a ring of light surrounded by long-haired dancers.

When it was time for Petras to join, she was unveiled in a red minidress and locked in a cage. RuPaul's Drag Race stars Gottmik and Violet Chachki joined the performance as dancers.

Smith and Petras looked great and sounded even better, and Kim even got to get some of her trademark “Woo”s in there!

Earlier in the night, the duo won the award for Best Pop Duo/Group Performance for “Unholy.”

Smith had asked Petras to give the acceptance speech for the award as she was the first trans woman to win the award.

“I just wanted to thank all the incredible transgender legends before me who kicked these doors open for me so I could be here tonight,” Petras said in her speech.

“SOPHIE, especially. My friend who passed away two years ago, who told me this would happen and always believed in me. Thank you so much for your inspiration, SOPHIE. I adore you and your inspiration will forever be in my music.”
