She's since recanted her statement about blaming her band and copped to the whole thing.
Here's a statement from her on the message board of her site:
Hello.
Please can everyone stop posting their asshat comments in new posts? The messages are intended for me to read, right? So, post them as a comment so i can read them all, and reply to as many as possible.
Right, now thats out of the way..
I know i said i'd never do it, and spoke down about lip-synching (LS), but i do not sleep very much (or haven't been doing much recently) and i have travelled a lot and done so many things, i have a lot on my mind with things that no-one else knows.. i did not feel up to it.
Imagine getting the chance to sing songs you wrote and recorded on SNL infront of millions. Then the day before, almost losing your voice or at least not being able to sing to your full ability (and before anyone says it, i can sing - so fuck you
It REALLY, can be, no fuck that, IS as simple as that.
See you all soon, and thanks for the support to the majority of people who are giving it.
