Olivia Newton-John to Guest Star on 'Glee'

Olivia Newton-John will appear on Glee this spring and singing “Let’s Get Physical” with Jane Lynch!

Glee creator Ryan Murphy filled Entertainment Tonight in on the show’s latest gossip at an InStyle party over the weekend.

“Olivia loves the show and is a great idol of mine,” Ryan shared.

After a much deserved break, the cast has begun filming again – Lea Michele tweeted on Friday, “On set shooting with my best friend Jon Groff!!! We’re having so much fun!! Can’t wait for you guys to see him on the show!!!”
