Two former stars of the hit TV series ‘Smallville’ allegedly used their celebrity status to recruit young women for a sex cult, according to a report. Kristin Kreuk and Allison Mack signed up with self-help guru Keith Raniere, leader of the NXIVM (pronounced Nexium) group based in upstate New York. Mack played a high school student with a secret crush on a young Superman. Kreuk played Clark Kent's love interest, Lana Lang. Raniere was arrested this week and was charged with sex trafficking.
