I think it was the lead singer. Also I am sure she really ticked off the other two but...they didn't have the guts to cut her lose. I am sure she sprung that on them by surprise as well. So, they are stuck with her and better them than the rest of us. Watch this song bomb out. They are still in t he attack mode. They didn't learn anything from before. I wonder if they will go on another mag cover in the nude like they did before. THAT really put them over the top didn't it? They have NO BRAINS.
The sisters didn't have a problem cutting loose their previous lead singer. Dropper her like a hot potatoe, picked up Natalie (right name?) from her father and jumped from folksy to pop/country to make their fortunes.
