Laura Vandervoort is swooping into “Smallville” this fall for a special final season episode that will have the stunning 25-year-old starlet reprising her role as Supergirl. Vandervoort was introduced as Superman’s Kryptonian cousin Kara Zor-El during the long-running hit show’s 7th season.

The Supergirl episode is scheduled to air in October and marks Vandervoort’s return to the series since appearing in season eight’s “Bloodline.” Producers for the CW program are also bringing back former series regular John Schneider (Clark Kent’s dad) for one or two episodes.

“Smallville” begins its tenth and final season on Sept. 24.

Vandervoort currently stars as alien-visitor Lisa on ABC’s “V.”
