"Bad Romance"

"Poker Face"

This week, the "Glee" kids threw their paws up to celebrate pop culture's biggest phenomenon -- well, besides the show itself. Lady Gaga got the full "Glee" treatment, from the series' stars donning Gaga-esque ensembles (Brittany's lobster headpiece, Kurt in those McQueen heels - ouch!) and writhing through "Bad Romance" to an intimate "Poker Face" performance between Rachel and her biological mother. If you think her two gay dads are proud, imagine how Mama Monster herself must feel!
