Glee returns to FOX on September 13, and, as you proabably already know (if you're into knowing these sorts of things), it will include Kate Hudson as a teacher. She debuts her character with Lady Gaga’s “Americano” mashed with Jennifer Lopez’s “Dance Again.” It's a fast-paced number, and we kinda think Hudson looks like the grownup Britney Spears we always hoped would happen. Or maybe she's stomping for Bebe Neuwirth's Broadway baby mantle. Watch out! Rachel (Lea Michele) looks none to happy in the clip below.
