Danity Kane seemed to be the "next big thing" for a brief while there.
I believe they got a couple of number 1 albums. All this until Puff cut two or so of them from the group (I can't remember why).
Interestingly, Aubrey O'Day had been saying some stuff about Puff but she's someone that's said a ton of stuff so it's difficult to know what's true or not.
EDIT: The board is insanely slow. It's like the old dial-up days.
