Olivia Newton John

Before she shimmied on the black leggings and told John Travolta he was the one that she wanted, Olivia Newton-John saw a shiny silver flying object whiz overhead at "amazing speeds." She explains, "I have seen a [UFO] when I was very young. It was unidentified and it was flying," she explains. "It's true that I'm intrigued by them. I have seen so many shifts in belief systems over the years. In England most people now think UFOs are possible. Twenty years ago, how many people would have thought that?" [Daily Telegraph]
