Olivia Newton John: Revealed she is fascinated with aliens after a close encounter with a UFO as a teenager. The ‘Grease’ actress claims she spotted a flying silver object which blazed across the sky at “amazing speeds” when she was a teenager. Olivia is convinced most British people share her belief in the existence of alien life. Describing her otherworldly encounter, the 60-year-old actress told Britain’s The Sun newspaper: “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 – In England most people now think UFOs are possible. Twenty years ago, how many people would have thought that?”
