Smallville star Kristin Kreuk has denied claims she recruited women to serve as “sex slaves” for a self-help organization recently accused of being a sex-trafficking cult. Kreuk, who joined the Nxivm group along with co-star Allison Mack in 2005, issued a statement on Twitter late Thursday saying she’d left before seeing anything “illegal or nefarious” take place. “I am deeply disturbed and embarrassed to have been associated with NXIVM,” she wrote. “The accusations that I was in the ‘inner circle’ or recruited women as ‘sex slaves’ are blatantly false,” she said, adding that she is “horrified and disgusted” about the group's alleged activities. Keith Raniere, Nxivm’s leader, was arrested in Mexico and charged with sex trafficking and conspiracy to commit forced labor earlier this week. Mack, who has been accused of acting as Raniere’s No. 2 and helping to recruit “slaves,” is thought to have been with Raniere when he was arrested.
