A cheetah playing peak-a-boo gave one photographer the opportunity of a lifetime to take some unbelievable photos.

Australian photographer, Bobby-Jo Clow, 31, who specializes in wildlife photography, was in the Serengeti National Park in Tanzania when a group of cheetahs approached her car.

According to Clow's Facebook page, a female jumped onto their vehicle, climbed up onto the open roof and smelled Clow's head - putting its paw just inches from her face.

"I tried to stand up but she hissed at me. This was probably one of the greatest moments of my life," Clow wrote.

Clow, who has been photographing wildlife for the past seven years, is now running photographic safaris to give others the opportunity to capture amazing photos.
