There was quite a bit of sarcasm in her voice. I strongly, STRONGLY doubt she'd make a comment like that in front of everybody. Judging by their reaction to her there were most definitely some inside stuff there since they all started cracking jokes when she made the comment. She was trying to make a joke about the cookies and flowers that were being sent but by the time she got to it everybody was talking all over each other. She was still smiling in the end which pretty much indicated to me that she was more amused than annoyed by it. I think she was advocating on behalf of Carly and Syesha. She never claimed to be one of the best singers.
They have to select an even number of boys and girls to perform on the show. Unfortunately they got a fantastic group of guys and the ladies had three anchors in the form of Amanda, Ramiele, and The Colonel. They didn't stand a chance even if they were better singers (Carly/Syesha) than the guys.
This season's outcome was influenced by the rabid female fans out there. Don't believe me? How many times did you ladies vote for DC? Yeah, that's what I thought.
