Joanna Pacitti. The official reason why she was disqualified is "conflict of interests". Plus she was no amateur.
Here's the cover of her album from a couple years ago.
And here she is back in 1997, when she was fired from "Annie".
Apparently this was such catastrophic news that ABC's 20/20 had to do an exclusive report on it.
Goodnight, everyone. Have a great weekend :)
