Even the biggest, most passionate fans of "Glee" probably wouldn't deny that the show has a huge and talented cast already in place and that the writers already have a hard enough time servicing that cast.
 
But when you have a budding teen idol and an Oprah-endorsed international singing sensation at your disposal, how can you not add new characters to the mix?
 
Meet Chord Overstreet and Charice, the two new faces of "Glee," both making their first appearances on Tuesday's (Sept. 21) second season premiere.
 
Overstreet's previous credits include "iCarly" and he's sure to have fans and critics throwing out a variety of names for the stars he most resembles (I'm going with Eric Christian Olsen). 
 
Charice, meanwhile, is already a YouTube phenomenon and a star overseas, though you may have seen her in guest appearances with Oprah and Ellen DeGeneres.
 
Note that this interview contains spoilers about the characters played by Overstreet and Charice. They're not live-changing spoilers or anything, but if you want to go into Tuesday's premiere fresh, you may not want to watch the video until after watching the episode.
