Salma Hayek back to '30 Rock' for series finale with Julianne Moore, Alec Baldwin

Salma Hayek is set to reprise her "30 Rock" Season 3 guest starring role as Elisa, one of Jack Donaghy's many love interests, in the show's series finale on Jan. 31.

Entertainment Weekly reports Hayek will join a previously announced Julianne Moore (who was involved in a Season 4 love triangle with Alec Baldwin's Jack and Elizabeth Banks' Avery) as a guest for the finale.

Obviously details of the finale are being kept under wraps but we do know that Nancy Pelosi and Ice-T are also involved, somehow. Speculate away!
