Carrie Underwood is allegedly ready to quit ‘’American Idol’’ unless producers increase her salary and handle her fan backlash better. A source says, “She got a lot of backlash, and she’s not used to that. Carrie’s always been adored by fans. This was a shock to her system. They know Carrie can grow into the role. But dragging out the negotiations is not a good look for a show this big. Carrie needs to tread carefully. If she comes off too demanding, it might hurt her reputation more than help.’’
