New Delhi Indo-Brazilian model Nathalia Kaur, who is grabbing eyeballs with her sizzling item number in Ram Gopal Varma's upcoming film Department, says the filmmaker is not her mentor or godfather. Apart from giving her an item number, the director has cast Nathalia in a leading role for his next romantic thriller. However, the model insists the equation she shares with Varma is nothing more than that of an actor and director. "Ramu (Ram Gopal Varma) is not my godfather or mentor. I am just working with him. He is a director and I am an actor," said Nathalia, who was in the capital for the promotion of Department.
