Rahul Sipligunj, who sang the Oscar-winning song 'Naatu Naatu' along with Kaala Bhairava, recalled meeting Rihanna at the award ceremony.
"She was observing that these two guys (Rahul and Kaala) wanted to take a picture but were too shy to ask for it," he said.
"Then she came forward and appreciated us and clicked pictures with us," Rahul added.
