Britney will not have one episode on Glee this season. She has two!
According to AOL, Britney's first tribute episode, "Britney/Brittany," airs second on Tuesday, September 28 at 8 PM EST. The report claims Britney's confirmed for the first episode during an "anesthesia-induced dream sequence at the dentist's office."
Britney is not confirmed for the second episode, but because it airs after the Superbowl, many fans speculate she'll have a considerably larger role for the follow-up episode.
