Susan Boyle is to star in a 'Glee' Christmas special.
According to show creator Ryan Murphy, Paul wrote to him personally to ask him to use his songs in the programme.
He told the BBC: "I received some fantastic mixed tapes from Paul McCartney a couple of weeks ago. I thought I was being punked!
"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 gob-smacked... so of course we are going to do something with him."
Ryan also confirmed rumours that the 'Britain's Got Talent' contestant - who shot to fame around the world after clips of her audition became online sensations - will appear.
It is believed she will play a dinner lady in the school, although Ryan wouldn't confirm exact details about her part.
