Here is the original audition contract, and some choice bits from it:
"I understand that I may reveal, and that others may reveal, information about me that is of a personal, private, embarrassing or unfavorable nature ..."
"... Information may be factual and/or fictional."
"(The show) ... May expose me to public ridicule, humiliation or condemnation."
And that the producers have these rights, "throughout the universe in perpetuity."
Any comment, former judge Paula Abdul?
