Smallville alum Allison Mack pleaded guilty in the NXIVM sex-cult case. She is facing a laundry list of charges, including sex trafficking, identity fraud and money laundering. She appeared sobbing before the judge.

“I’m here to plead guilty before your honor,” the actress said through sobs, with Judge Nicholas Garaufis finally stopping her to offer her tissues.

“I must take full responsibility for my conduct. I am very sorry for my role in this case. I am very sorry to my family and to the good people I hurt through my misguided adherence to NXIVM leader Keith Raniere’s teachings,” she later continued.

She said the system was “designed to make them think they could suffer serious harm” if they didn’t do what she said.

Mack was involved—and allegedly helped run—an Albany-area master-slave sex ring. She previously pleaded not guilty and faces up to life in prison.

Mack, 36, is the third person to plead guilty after Lauren Salzman, 42, her mother and NXIVM co-founder Nancy Salzman, 64. The so-called cult was led by Raniere. He and five leaders of NXIVM were indicted last year; the remaining defendants are operations director Clare Bronfman and Seagram’s heiress Kathy Russell.
