In his own words, "What a funky lady."
The androgynous Aerosmith frontman, and former Idol judge, appeared before the current panel of Nicki Minaj, Mariah Carey, Keith Urban and Randy Jackson as the show combed through hopefuls in Oklahoma City.
He wore a blonde wig, a snakeskin skirt, and an apparatus that created the illusion of a bust, complete with honking effects.
"What the what?" a confused Randy said as the 64-year-old rock icon emerged as his garish alter ego.
"I'm gonna judge your a** first," the Dude Looks Like A Lady singer said. "Unlike you men, the roosters may crow, but the hens deliver the goods!"
"You wanna go through to Hollywood or what?" Randy said. "I thought it was Halloween up in here!"
After some playful dialogue with the judges, Tyler lost the wig and wished the current panel good luck in following his footsteps.
"No Hollywood for you -- maybe Boston!" Randy told the Beantown native.
"Oh hell naw," Nicki said. "That is a sight to be seen!"
