Actress Samia Shoaib reveals that she was befriended by Allison Mack in hopes of recruiting her to the Nxivm sex cult she's part of.

Mack was arrested for her alleged role in a sex cult last Friday, April 20.

Shoaib Speaks Out On Experience With Mack

The Pakistani-born actress tells The Post that she met Mack during an audition for a television pilot in 2013.

"I wish I could tell you alarm bells went off, but they really didn't," Shoaib shares, calling Mack "a very sweet girl."

Upon learning of her fellow actress's involvement in Nxivm, Shoaib remembers the time when Mack reached out to her after their initial meeting.

"Is there anything you have read that you can send to me?" Mack says to her in an email in March 2013. "I would love to get into your brain a bit?!"

In a later email, the actress also called Shoaib and her friend "delicious women" after their last meeting.

Shoaib, 47, recalls how the Smallville star seemed desperate at the time, but not dangerous. The pair met in person twice, once at a restaurant on Amsterdam Avenue and another at Shoaib's own apartment in the Upper West Side.

Mack looked increasingly gaunt and fragile with each meeting, Shoaib continues, adding that the alleged sex cult leader seemed to be physically suffering and sleep deprived.

The two of them would talk about feminism and Mack would bring up a Nxivm-affiliated women's group, but she'd always be vague about the group.

"[She'd say] 'It's a bunch of women. We go on a retreat upstate, and we share our experiences and support each other,'" Shoaib recalls.

Eventually, Mack backed off and Shoaib suspects her retreat was related to her age.

In a Twitter post after her interview, the Sixth Sense star says she felt talking about her experience with Mack was her responsibility.

Mack's Arrest

Mack, 35, was arrested for sex trafficking for her alleged involvement in the cult-like Nxivm group. If convicted, the actress could be subject to up to 15 years to life imprisonment.

Apparently, the Smallville actress is considered one of the "masters" of the so-called sex cult with the role of recruiting "sex slaves" for the group.

Nxivm leader Keith Raniere has already been arrested ahead of Mack in March. It's reported that Mack had an intimate relationship with the leader.
