Former 'Dance Moms' star JoJo Siwa shocked fans on the red carpet at the 2024 iHeartRadio Music Awards sporting a jaw-dropping heavy metal-inspired look.

Siwa, 20, whose fans said she was nearly unrecognizable on TikTok, is expecting criticism from haters, telling E! News that her next musical era would be for "more mature audiences."

"People are afraid of things they don't know," Siwa told the media outlet. "Things can be scary for people. New things can be very, very scary."

Former KISS rockstar Gene Simmons defended her look — which debuted her self-proclaimed "Not Made For Children" era — and KISS-like appearance.

In an interview with TMZ, Simmons, 74, didn't mind the comparisons, saying he likes the "demon" look, explaining that anyone who is hating on her simply doesn't get it.

"Never be ordinary. Always be extraordinary," he said. "JoJo is extraordinary and she looks cool."
