Longtime Scientologist Nancy Cartwright -- best known as the voice of Bart Simpson -- last year gave the church $10 million to help spread the word of founder L. Ron Hubbard into other galaxies.
It was all part of Scientology's Global Salvage effort, which aims to "de-aberrate" Earth -- meaning to rid mankind of psychology ills and other "aberrant" behavior.
Surprisingly, Nancy, 50, forked over twice as much as the Scientology's most prominent member, Tom Cruise, who only gave $5 million in an installment plan.
In 2004, the 46-year-old Lions for Lambs actor was awarded a Platinum Meritorious Award for a $2.5 million gift. Two years later, he doled out another $2.5 million, for which the International Association of Scientologists kicked him up to Diamond Meritorious awardee.
