Australian zookeeper Mark Mills has been dubbed the rhino whisperer, after lulling to sleep a baby white rhino that had been rejected by its mother at birth.
The adorable footage of Mr Mills playing a gentle song on his guitar to the baby rhino was filmed at a sanctuary in South Africa and has quickly made its way around the globe.
The sanctuary rescues rhinos orphaned by poaching and raises them in a safe and secure environment until they can be released back into the wild.
