We’re already learning about the first tribute episode in Glee’s fourth season, and the decision was made because of the big Britney Spears news yesterday.

The second episode of season 4 will pay tribute to Spears using eight of her songs. Fox wants the second tribute episode because of the singer joining their X Factor as a judge. According to the Fall schedule, X Factor will lead into Glee on Thursdays.

Are you interested to see a second episode with Spears, or is it overkill? At least by putting the tribute episode very early on in the season, it won’t greatly disrupt any potential new plot lines. Brittany will reportedly not be part of Spears’ plotline, as was the case in the first tribute.

We learned yesterday that Glee will be moving to Thursdays in the Fall, and the graduating characters will be part of a “show within a show.” Sarah Jessica Parker and Kate Hudson are the first announced guest stars.
