Sam Smith and Kim Petras stole the show Sunday at the 65th Annual Grammy Awards with a performance viewers are calling "demonic" and a "tribute to Satan."
Smith and Petras, who went on to take home the award for Best Pop Duo or Group Performance, took the stage to perform "Unholy" wreathed in red amid fire and red lights.
The 30-year-old Smith wore a horned hat and dog collar while his dancers used "props that had allusions to BDSM themes," according to a report.
"Unholy" has many sexual themes and name-drops Balenciaga, a fashion house continuing to face backlash over a controversial ad campaign that featured young children and BDSM props.
