Gwyneth, Cheno, Gaga, Oh My!

You read correctly! Gwyneth Paltrow AND Kristin Chenoweth WILL be back for multi-episodes! Lady Gaga's music will also be featured, again!

POSSIBLE SPOILERS BELOW!

Ryan Murphy stated that he would like to bring Holly Holiday back and lucky for us, he is!
Ry-Murphs had this to say:

"Gwyneth is coming back for two episodes. She’s coming back specifically to date Will [Matthew Morrison]. Those two have become really good friends in real life and had really good chemistry. She’s coming back as a sex education teacher. Gwyneth and I are emailing, talking every week: What are we gonna sing? We’re trying to do something fantastic. So she’ll be [in episodes] 15 and 16. She comes back [to film] in January and she’s with us for three and a half weeks I think."

He also stated that K-Cheno will be back at the end of Season 2's finale!

Lady Gaga's soon-to-be new single Born This Way will also be featured in an episode centered around Dave Karofsky:

"I love that that song is anthem. This show is by nature optimistic and I think a character like Karofsky could turn to booze or pills or alcohol and kill themselves or do something dark. But I also love Max and I love that character and I sorta want that character to have a happy ending. So I don’t really know what that’s going to be, but I do know we’re going to do a whole episode that’s about that song."

I'm SOOOO excited!!! I CAN NOT wait for Glee to come back in February!
