Ryan Murphy, the creator of “Glee” said “I have two words for you: Lunch. Lady. I think Kurt would just die to give her a Christmas makeover. I don't even know if she's interested but it's been pitched."
Murphy also mentioned the possibility of a “Glee” Christmas album which would be released for Christmas 2010. Neither Boyle’s appearance nor the album has been confirmed.
I’m sure Fox would not be complaining about their ratings if they managed to pull that combo off.
