Watch Two Musical Numbers From Tonight's 'Glee' (Including Beyonce's 'Run the World')

Can't sit still? Can't wait? Absolutely need a little taste of "Glee" before the episode "Asian F" premieres tonight?

Well, learn some patience. It's a virtue. In the meantime, we'll enable you. And to be perfectly honest, these two musicals numbers are certainly worth an early look.

First, Mercedes (Amber Riley) gets to bring center-stage her voice big and strong enough to move the Earth with Jennifer Hudson's "Spotlight." It's pretty refreshing. For what little "Glee" I've watched, the voice it's frustrated me with not putting more in its own "spotlight" is Riley's.

Of all the people who could possibly go toe-to-toe with Riley at her best for fierce sassiness . . . Heather Morris? Really? Believe it.

Brittany brings the heat with her rendition of Beyonce's "Run The World" that makes a statement about her student office ambitions. She's come many a mile since her adorable-idiot days of the show's first season.
