America's Got Talent 2013 judges were shocked to hear some growling vocals from a Aaralyn, a sweet little 6-year-old girl singing "Zombie Skin," an original piece. The little girl performed with her old brother in the drums. Mel B said Aaralyn "officially scared" Scary Spice.

"When we go out there, we go and smile and be proud, and not be nervous," Aaralyn tells her brother in the AGT video clip. The adorable little girl comes to the stage wearing pink stockings under a polka dots skirt. The judges and the audience looked like they expected to hear the quieting, soothing voice of a little angel. Little did they know that Aaralyn likes irony. The siblings' dad was visibly amused, and the audience gave the kids a standing ovation.

"It's not because I didn't like (Zombie Skin). I was afraid your voice was gonna blow out," Howard Stern tells the Aaralyn. "That song really packs a punch," he continues.

"I'm really confused," Heidi Klum says. "You're so cute and sweet, and when you open your mouth, I was like, 'Whoa!'" She then asks to meet the parents, and dad comes out looking amused by his kids' America's Got Talent surprise.

"Scary Spice is officially scared," says Mel B, who adds it's all she could say. Mel B and Howard pushed their buzzers a bit too early, if Howie Mendell's reaction would be considered.

Howie tells the girl of how people would react to Zombie Skin. And he's right. Zombie Skin quickly became a hot Twitterverse topic. One thing seems obvious though, the sweet 6-year-old knows her music.
