Because it always make sense to plan your storylines around other shows...

Following the confirmation that Britney Spears will judge season two of The X Factor, Entertainment Weekly reports that Glee is planning its second tribute episode in honor of this pop superstar.

It will be the second installment of season four; it will feature eight Britney tracks; but, unlike the original Spears tribute, it will not center around Heather Morris' Brittany S. Pearce.

Elsehwere, Chris Colfer appeared on Live! With Kelly this morning and discussed the casting of Sarah Jessica Parker and Kate Hudson more in depth. He confirmed that the former will serve as a mentor of sorts for Kurt in NYC next season, while the latter will do the same for Rachel.

Each actress will appear on multiple episodes and Hudson will be featured in many dance routines.
