In a new seven-episode podcast from CBC's "Uncover," titled "Allison after NXIVM," hosted by Natalie Robehmed, Mack, 43, opens up about her time in NXIVM, a cult-like group that purported to be a self-help organization.

In a recent statement, Allison said her Smallville costar Kristin Kreuk, who played Clark Kent's love interest, Lana Lang, on the show, was the one who introduced her to NXIVM.
