Tricia Helfer, the siren of ‘Battlestar Galactica’

Tricia Helfer as Number Six, the seductive humanoid Cylon robot on the TV show Battlestar Galactica, which ran from 2004 to 2009. At first, Number Six lures humans to their doom, but later she switches sides somehow or other. This photo is from the first releases of PR for the show in the fall of 2004. Tricia Helfer was born in 1974, so she turned 30 the year this photo was taken.
