A family on vacation in the Serengeti got a once in a lifetime selfie - with a cheetah. Thirteen-year-old Leilani Youmans came face-to-face with the predator, as it neared inside through an open sun roof. The brave teenager calmly posed and smiled as other guests took her picture. Thankfully, the cheetah and its mate had just hunted down, killed and eaten - meaning they were not remotely interested in the tourists.
