"Glee"  diehards were treated to more season two spoilers  at a Sunday (July 25) afternoon panel at San Diego Comic-Con, where co-creator Ryan Murphy shared details about the hit series' much-anticipated Britney Spears episode .
"The episode will be called "Britney/Brittany," Murphy said, adding that the episode's plotline will poke fun at Matthew Morrison (who plays Mr. Schuester) and his admitted reluctance to devote an entire episode to Spears. "The entire episode is Mr. Shue saying, "I don't want to do Britney"...The cast is getting this episode tomorrow actually; it's hot of the presses. We're doing it in a really fun, hallucinogenic way." The Spears episode follows last season's tributes to Madonna  and Lady Gaga .
Murphy also confirmed that "Glee" will take on the campy tunes of the cult film "The Rocky Horror Picture Show" in an upcoming episode, and that the musical numbers featured each week will be reduced from 8 to 5 in order to make more room for developing characters. "It got to be a little much," Murphy says of the musical numbers. "People loved the characters so much that they want to spend more time with them, so we listened and that's what we're going to do.
In addition, "Glee" recently announced the casting of newcomer Chord Overstreet in a recurring role as Finn Hudson's (Cory Monteith) protégé-turned-nemesis, as well as impending guest roles  by singer Charice  and actor John Stamos.
The smash musical show's second season premieres Sept. 21 on Fox, and picks up from a first season that recently earned 19 Emmy nominations. Meanwhile, "Glee: The Music, Volume 3: Showstoppers" clocks in at No. 34 on the Billboard 200 this week, with four other "Glee" titles currently on the chart.
