Probably not. This appears to be a management decision. Nothing personal, it's just business.
On a related note, I saw Clarkson as the musical guest on Saturday Night Live. IIRC, this was shortly after the Ashlee Simpson lip-synching fiasco. One thing was for certain, Clarkson was not lip-synching. She belted out a screaming version of "Since U Been Gone" and that girl has some pipes! Damn near gave me goosebumps!
