Allison Mack is blaming one of her former Smallville co-stars for introducing her to NXIVM! Two years after being released from prison early, the actress opened up about how she got involved in the sex cult on the Allison After NXIVM podcast on Monday. You may recall that shortly after the arrest of co-founder Keith Raniere, a report dropped claiming Kristin Kreuk lured other women into the group after she joined around late 2005 - including Allison.
