The “Knight & Day” megastar, who regularly pals around with Church of Scientology head David Miscavige, has been dragged into an FBI investigation of human trafficking and unpaid labor involving the controversial Hollywood-centric sect and its boss.

Miscavige, who served as Cruise’s best man at his wedding to Katie Holmes, is under investigation for reportedly paying church members chump change to do work on Scientology property and a building, an SUV and two motorcycles owned by Cruise. And while his staffers reportedly were paid just $50 a week, Miscavige enjoyed a luxurious lifestyle of chartered jets, expensive cars and two personal chefs, according to an expose in The New Yorker.
