Move over, Dr. Foster: There's a new woman gunning for Cal Lightman. Battlestar Galactica's Tricia Helfer will guest-star on a Season 3 episode of Fox's Lie to Me, TVGuide.com has learned exclusively.

Helfer will play Naomi, who is attracted to Lightman (Tim Roth), despite being frustrated by her inability to hide anything from him. When she calls on Lightman for protection from a violent ex-boyfriend, Lightman begins to wonder if her beauty has impaired his lie-detecting skills.

Best known as Cylon Number Six on Battlestar, Helfer, 36, currently stars opposite Dylan McDermott on TNT's Dark Blue. She has also recently guest-starred on USA's Burn Notice and the series premiere of Fox's Human Target.
