Petition Against Ashlee Simpson

The petition, addressed to Simpson’s record label Geffen Records and JT Entertainment, her father Joe’s management company, reads, "We, the undersigned, are disgusted with Ashlee Simpson’s horrible singing and hereby ask her to stop.

It adds that "she cannot match the sound of her voice that can be found on her CDs when she sings live. She simply yells the words (sometimes the wrong ones) into the mic."

Ashlee Simpson is launching her first American tour next month for her next album Pieces of Me.
