Allison Mack tied the knot with reformed neo-Nazi Frank Meeink two years after her release from prison. The former Smallville star served 21 months behind bars for pleading guilty to racketeering and racketeering conspiracy due to her involvement in the self-help group-turned-sex cult NXIVM. Mack was accused of recruiting for the secretive all-female NXIVM subgroup known as Dominus Obsequious Sororium (DOS), in which members - who called themselves "slaves" - had cult leader Keith Raniere's initials branded on their skin and were allegedly pressured to seduce Raniere.
