"I always dreamt of becoming an actor and continue to live that dream. Singing happened out of obligations for friends and people whom I consider my well-wishers. Neither am I a trained singer, nor take it as a career interest," Nakul told IANS.
"Director Shankar made me a singer. He found my voice apt for one of the songs in Anniyan. Since then, I have been singing once in a while for most of my composer friends such as AR Rahman sir and Harris Jayaraj sir. I'm lucky that most of my songs have been very well received," he added.
Nakul has also crooned 'Nakula...' for his upcoming Tamil action-drama Vallinam.
"I don't even consider that I have a voice suitable for singing. I'm more or less a bathroom singer like many others, but I wonder what these composers find in my voice that they make me sing occasionally. I haven't turned down any singing opportunity because it has mostly come from my friends," he said.
He has also sung in Tamil films such as Ghajini, Vallavan and Kandhakottai.
