Actress Allison Mack has alleged that her former Smallville co-star Kristin Kreuk was the one who introduced her to the NXIVM organization, which was later exposed as a sex cult, as reported by the New York Post.
During the debut episode of her new podcast Allison After NXIVM, released this week, Mack, 43, claimed that Kreuk, 42, first brought her into contact with the Albany-based group, originally promoted as a self-help and leadership organization. NXIVM’s founder, Keith Raniere, is currently serving a 120-year prison sentence for sex trafficking and racketeering.

Mack, who served 21 months in prison for her role in the group, is now detailing her experiences in a seven-episode podcast series. She recounted her friendship with Kreuk during their years on Smallville, including shared travels and personal struggles.
“We went to Syria and Turkey together, we went to Mongolia together, we went to Paris, and we had so much fun,” Mack said. “We went to Paris multiple times together and just shopped and saw art and sat on the top of the Pompidou and had rosé and lived this kind of dream.”
She added that by their mid-20s, the two were living in New York City and both felt “oddly unsatisfied.”

Mack recalled, “We both were at the point where we were 25, we were in New York City together, it was our break. And we rented an apartment in the same building in the West Village, and we both were like, ‘Why do we feel so unsatisfied?’”
According to Mack, Kreuk eventually told her about a course she had taken through NXIVM while filming in Vancouver. “‘It’s the science of joy. It’s the most amazing thing,’” Mack recalled Kreuk telling her. “‘It’s made everything so much better in my life. You’ve got to do this.’”
“It was all she could talk about,” Mack said. “She was super excited about it.” Kreuk allegedly invited Mack to attend a weekend retreat, telling her, “‘They’re doing a weekend and I think you should do it. I think you’d really like it.’”
The allegations come years after Kreuk publicly distanced herself from NXIVM. In 2018, she issued a statement denying involvement in any criminal activities connected to the group.
“When I was about 23, I took an Executive Success Programs/NXIVM ‘intensive,’ what I understood to be a self-help/personal growth course,” she wrote. “I left about five years ago and had minimal contact with those who were still involved.”
Kreuk added, “The accusations that I was in the ‘inner circle’ or recruited women as ‘sex slaves’ are blatantly false. During my time, I never experienced any illegal or nefarious activity. I am horrified and disgusted by what has come out about DOS.”
NXIVM, founded by Raniere and co-founder Nancy Salzman, drew thousands of members with claims of personal empowerment.
Prosecutors later revealed that within the group, a secret sect called DOS—short for Dominus Obsequious Sororium (“master over slave”)—used coercion, starvation, and blackmail to control female members, some of whom were branded with Raniere’s initials.
Mack was one of the highest-ranking members of DOS, accused of recruiting and supervising women for Raniere. In 2019, she pleaded guilty to racketeering and racketeering conspiracy and was sentenced to three years in prison in 2021. She was released early in 2023.
At her sentencing, Mack apologized to the women she recruited, calling her involvement “the biggest mistake and greatest regret of my life.”
