Allison Mack: Witness says actress starved ‘Dyansty’ star’s daughter for a year to get her down to ideal sex-slave weight

New allegations have emerged against former “Smallville” star Allison Mack, who has been linked to a sex cult known as Nxivm.

As CrimeOnline previously reported, both Mack and the cult’s alleged leader, Keith Raniere, were arrested last year on suspicion of sex trafficking and forced labor conspiracy, with each facing up to 15 years in prison if found guilty.

A woman who described herself as a former member of Nxivm testified last week about abuse she allegedly witnessed at Mack’s hands, according to the New York Post.

Identified only as “Nicole” during testimony in Raniere’s trial on Friday, the witness said Mack manipulated the adult daughter of actress Catherine Oxenberg, known for her starring role in “Dynasty.”

Mack’s goal, Nicole claimed, was to get India Oxenberg “down to a certain weight,” which cult leaders allegedly determined to be 107 pounds.

In order to achieve the goal, the witness said Mack placed Oxenberg on a starvation diet for a year.

“When India and I became close, they would use her to make me behave,” Nicole said, claiming that Mack would regularly threaten to starve Oxenberg beyond the restrictive diet consisting of just 500 calories a day.

“It was just really hard to watch, sometimes,” Nicole said, adding that the experience “was tough on” Oxenberg.

Describing Mack as her “master,” the witness claimed that the actress would regularly humiliate members — including forcing them to pose naked each week for “family photos” she believed would then be delivered to Raniere.

Mack allegedly used the friendship between the two cult members after Nicole decided to leave Nxivm.

“The first thing Allison said is, ‘Look what this is doing to India; she hasn’t eaten since she got your email,'” according to Nicole’s testimony. “And India said, ‘Well, that’s not entirely true.'”
