Olivia Newton-John at Waterstones in London

From Olivia's recent book signing in London for her cookbook "LivWise."  All proceeds of the book go to help build the Olivia Newton-John Cancer and Wellness Centre in Melbourne, Australia.

I am always fascinated by the flashes of the photographers. I don't know why.  I also think it's funny how they yell at celebrities.

I do laugh when Olivia tries to stop them, say "I'll start over here and work my way across" so they all can have a direct shot, and then they just do what they were doing anyway. Take charge Miss Olivia!
