Could Jennifer Lopez and Jim Carrey be the latest high-profile converts to Scientology by Tom Cruise?

Lips flapped when J. Lo and funnyman Carrey were very visible guests at TomKat's Italian wedding extravaganza, with many wondering where their friendships might have started. But now, says Page Six, it appears that the "mystery link" might be the Church of Scientology. Carrey is taking the introductory and beginner's courses right now, says a source, and Lopez has started talking the Scientology talk via her BFF Leah Remini, an avowed Church member.

Problems may emerge, however, as Lopez's husband Marc Anthony is a devout Catholic (though that didn't stop Katie Holmes). J. Lo's rep had no comment, and Carrey's flack says he's not taking classes.
