Abdul is "hurt" and "angry" about the situation, according to Sonenberg, who began managing Abdul late last month.
"She's not a happy camper as a result of what's going on. She's hurt. She's angry," Sonenberg told The Times. "I think at this point we're going to be considering everything, including some kind of a competition show. She has tremendous ideas for a whole variety of shows."
Earlier this month, Abdul told The Associated Press that she had been invited to continue serving as an American Idol judge until the show goes off the air, pending an agreement on a new contract.
However no contract proposals have followed the invitation, according to Sonenberg.
"I find it under these circumstances particularly unusual; I think unnecessarily hurtful," he told The Times. "I find it kind of unconscionable and certainly rude and disrespectful that they haven't stepped up and said what they want to do."
Fremantle, 19 and Fox all declined to comment on Sonenberg's statements.
DioGuardi signed only a one-year deal for the show's recently completed eighth season, which also represented the last year of a three-year contract Abdul signed with Fox in March 2006.
American Idol's ninth-season call-back auditions -- the first in which auditioneers get to perform in front of the show's actual judging panel -- are scheduled to begin August 6, according to The Times.
