I guess if she is described as "failed" then it must be an American site (but would they rate her b-) and surely she is a "singer"?
However if going with that guess then I would assume the trash talker would be the judge who went from host to replacement on the series the original "failed" on.
She's the only one i thought of. She got sent over there & then got given the boot. So from a U.S point of view i guess she is.
