LATEST: The original Buffy The Vampire Slayer, Kristy Swanson, is pressing assault charges against the ex-wife of her current boyfriend, skater LLOYD EISLER. The actress was arrested over the weekend after love rival Marcia O'Brien filed a complaint against her with local police in Ontario, Canada. O'Brien charged she was the victim of an attack by Swanson. The actress insists it was O'Brien who attacked her - in front of the children she shares with ex-husband Eisler. Eisler left O'Brien, who was pregnant with their second child, after falling for Swanson while the couple recorded reality TV show Skating With The Stars last year (06).
