“Smallville” actress Allison Mack was accused of recruiting women into a sadistic upstate sex cult and has since pleaded guilty to racketeering and conspiracy charges.

Mack was charged with tricking women into joining NXIVM by reportedly telling them that it was a self-help group. The Albany-based operation was founded by Keith Raniere, who is said to be a “charismatic perv,” also accused of possessing child pornography.

“I joined NXIVM to find purpose. This past year has been one of introspection and self-examination,” she said after crying in Brooklyn federal court. “It’s been a year of looking at what I’ve done the past 10 years.”

“I have come to the conclusion that I must take full responsibility for my conduct and that is why I am pleading guilty today,” Mack told Judge Nicholas Garaufis.

36-year-old Mack will face a maximum of 40 years in prison when she’s sentenced on Sept. 11. Each count to which she pleaded guilty carries a maximum penalty of 20 years in jail, three years post-release supervision and a maximum fine of $250,000, according to Daily News.
