Can she act? Susan Boyle is set to appear in the next season of Glee, according to the show’s creator Ryan Murphy. He says she’ll appear in a Christmas episode as a “dinner lady.” Also, Murphy says Paul McCartney has offered the show his music. "It came out of the blue in a package, handwritten, and it had two CDs and it said 'Hi Ryan, I hope you will consider some of these songs for Glee ...' I had heard that he is a fan of the show. I was gobsmacked ... so of course we are going to do something with him," Murphy said.
