Pneumonia forces Stevie Nicks to cancel publicity drive

However, she has been ordered to stay in bed after falling ill with pneumonia and influenza.

In a statement, Stevie Nicks says, "I want to apologize to all my fans and hope that we can reschedule, and of course I hope you love the new album. It's for you."

But the singer will be able to catch Tuesday's (03May11) Glee episode from her sick bed - the show is a tribute to Fleetwood Mac's iconic Rumours album.
