With Smallville heading into its final season, a couple of alums have booked their returns to the show.

We've already announced that John Schneider will reprise the role of Clark's adoptive father for at least one episode this fall - and now Michael Ausiello confirms an appearance by Laura Vandervoort on The CW hit.

The V star will show up in October, again taking on the role of Clark's super cousin, Kara.

Vandervoort exited the series at the conclusion of of season seven, but returned briefly the following years to wrap up Supergirl’s storyline.

Smallville returns with new episodes on Friday, September 24.
