Kristy Swanson

"Skating with Celebrities" star Kristy Swanson was arrested last night for allegedly assaulting the ex-wife of her current boyfriend and "Skating" partner Lloyd Eisler. People magazine reports that Swanson claims she was attacked by Eisler’s ex Marcia O’Brien, though no charges have been filed against O’Brien.

Drama erupted between Swanson and O’Brien last year when the original Buffy the Vampire Slayer began an affair with the very married Eisler, who eventually left O’Brien for Swanson, and the pair now have a son together.
