VIDEO: Steven Tyler 'Auditions' on Last Night's AMERICAN IDOL

Steven Tyler, dressed in drag, was the very last audition featured on last night's episode of AMERICAN IDOL. Dressed with faux boobs, and wearing makeup along with a blonde wig, the former Idol judge introduced himself...er...herself, as 'Pepper', an aspiring singer.

Mariah Carey, Nicki Minaj, Randy Jackson and Keith Urban immediately caught on to the gag, especially when he dramatically pulled off the wig and mooned the camera! Check out the "audition" below!

American Idol has been the No. 1 entertainment program among Total Viewers for the past nine consecutive seasons.
