'Glee's' Jane Lynch: Sue Sylvester is humiliated, Olivia Newton-John feels her pain

Jane Lynch just recently lived out a personal fantasy, working with Ms. Olivia Newton-John, which we'll see on "Glee" this spring.

However, Lynch gives us a little preview of their episode in the clip below.

"Olivia Newton-John is a charmer," she says. "She's as wonderful as in your fantasies you hope she would be... she plays [herself], Olivia Newton-John, who calls Sue Sylvester because one of my videos that I made for myself gets on YouTube and I'm humiliated at school. It's me doing a Jazzercise routine... Olivia Newton-John gets wind of it and calls Sue Sylvester and says, look, I saw your ridiculous video on YouTube. I did a ridiculous video, it's called the 'Physical' video. What say, we get together, redo it for a new generation? So that's how it happens."
