Jennifer's curiosity about Scientology is believed to be the reason that she and her husband Marc Anthony were invited to Tom and Katie's ultra-exclusive Italian wedding last month. Jennifer's family is very suspicious about the faith.

A source close to the family told the National Enquirer, "Jennifer, who's been a Catholic since birth, was told in no uncertain terms by her mother Lupe and other family members that exploring Scientology could backfire on her. They fear Scientology could damage her reputation."

The Lopez family is particularly skeptical about Jennifer's involvement in Scientology because they believe that the group may be using her. The insider said, "Her mom told her that the Church of Scientology would love to have her as a member because they could use the publicity to recruit new followers."
