Gene Simmons did not get the warmest reception during his judging on Dancing With the Stars.

Simmons, who fittingly served as a guest judge for Tuesday evening's Hair Metal Night, received a chorus of boos after revealing his score for Reginald VelJohnson, who danced a cha cha to “I Wanna Rock” by Twisted Sister with pro partner Emma Slater. The pair received a generous 6 from Carrie Ann Inaba, and then 5s from fellow judges Derek Hough, Bruno Tonioli, and Simmons.

The crowd first started expressing their displeasure when Hough revealed his score card, but booed particularly loudly when Simmons continued the trend.

Prior to the tallies being announced, Simmons had some kind words for VelJohnson, who told co-host Julianne Hough that he had channeled the iconic Kiss rocker for his performance. "Hey Reggie, you've got a beautiful woman right beside you who can twist it and turn it and knows how to move it and all that," Simmons said. "But I want to tell you, as a guy that's been on the stage for half a century around the world, I'm kind of a big deal, Reggie. It's all in the attitude. And you've got something in that beautiful face. They love you."

Though VelJohnson, 72, has consistently gotten scores on the lower end of the pack so far in season 33, Inaba also pointed out that he's been a fan favorite in her remarks. "You blow my mind, okay?" she told VelJohnson and Slater. "There's something about you that is just so engaging to watch. You're doing the fewest steps of anybody else in this competition, but somehow we're all so with you, and that is worth mentioning, right?"
