Lindsay Hartley and Justin Hartley

Lindsay Hartley, real-life wife of Justin Hartley (The Green Arrow), has been cast in the final season of Smallville, TVGuide.com has learned.

"Her character is a woman who takes matters into her own hands," says executive producer Kelly Souders.  "And those hands are wickedly dangerous!  She won't be working with Justin but she'll have her hands full with Clark!"

Hartley will appear in Episode 8, which is titled "Abandoned."

"We are thrilled to have Lindsay on Smallville," Souders says. "We've all been looking for a fun opportunity for the last year. "

Smallville returns Friday at 8/7c on the CW.
