“Grease” star Olivia Newton-John is a staunch believer in the existence of aliens. She even claims to have been visited by one as a child. "I have seen one when I was very young. It was unidentified and it was flying. It's true that I'm intrigued by them. I have seen so many shifts in belief systems over the years,” Newton-John told Britain's The Sun newspaper. "In England most people now think UFOs are possible. Twenty years ago, how many people would have thought that?" —XFINITY Entertainment Staff
