American Idol champ Ruben Studdard has filed a complaint with authorities in Birmingham, Ala., accusing his ex-manager of identity theft and forgery. Studdard claims Ronald W. Edwards forged paperwork giving himself power of attorney and used Studdard's credit cards to take $105,000. In February, Studdard sued Edwards for misusing more than $246,000 of his money. Edwards denied the claims.
