The Buffy the Vampire Slayer actress and the former Olympic figure skater met in 2005 as partners on the Fox reality ice skating competition.
The couple began dating even though Eisler, 45, was still married at the time and his wife was pregnant. In June 2007, Swanson, 39, was arrested for allegedly assaulting her lover's ex but the charges were later withdrawn.
The newlyweds have a 2-year-old son, Magnus. Eisler has two young children from his previous marriage.
