The Simpsons producers have denied any involvement with a Scientology-promoting voice mail recorded by Nancy Cartwright, who has provided the voice of Bart Simpson for 20 years, in which she advertises her current auditing level--new OT VII--and invites recipients of the message to the church's Flag World Tour event Jan. 31 in Hollywood, at which Cartwright is scheduled to speak.

But while her show might not be connected to the call, she sure didn't mind connecting her call to the show. The message begins with her saying, "Yo, what's happenin' man, this is Bart Simpson. Haha. Just kidding, don't hang up, this is Nancy Cartwright."

"It's gonna be a blast, man," she teases, sounding like Bart again, after providing the where and when.

But just because this particular Scientologist has a signature voice to help spread the word, it doesn't mean she speaks for anyone else. "The Simpsons does not, and never has, endorsed any religion, philosophy or system of beliefs any more profound than Butterfinger bars," said executive producer Al Jean in response to the implied connection.
