Karthika while speaking said," My mother Radha is my role model. I have watched her films in DVDs. I have also seen her acting in the song sequences. My first film in Tamil is Ko. I am donning the role of a journalist. I am doing the role which my mother has not done. There is nothing wrong in glamour. As far as I am concerned glamour is not in wearing costumes. It is not in wearing swim suits. It depends on the character’s style and acting.
After seeing the trailer of Ko many told me that I have acted glamorously in it. But in the most of the scenes, I have acted wearing saree and churidhar. "
