Scientology founder, L. Ron Hubbard's granddaughter, Roanne Leake, and current Church leader, David Miscavige's father, Ron Miscavige Sr. have both defected from Scientology's International Base near Hemet, Calif., according to a new report.

The Church Of Scientology has been at the center of a media firestorm since Katie Holmes filed for divorce from Tom Cruise. As previously reported, the President of Scientology's Ex-Wife, Karen de la Carriere told Breaking Celebrity News that the organization is a "pay as you go religion," and she donated more than $300k to the church.

According to the Village Voice, "Roanne Leake, who is L. Ron Hubbard's granddaughter, has 'blown' the base, which was her home for more than 20 years. But just as shocking, at about the same time, the base was also abandoned by David Miscavige's father, Ron Miscavige Sr."

It could be a devastating blow to David Miscavige as his father introduced him to the religion when he was 12 years old. Miscavige's brother, Ronald Jr., and his daughter, Jenna Miscavige Hill, also left the religion. Jenna has been publicly very supportive of Katie Holmes' decision to divorce Tom Cruise.
