Kamaal had claimed that the actress had made the controversial statement - "Rape is not a crime, it's just a surprise sex".
"I have filed a complaint with cyber crime investigation cell against KRK asking them to take action," Sunny, who filed it on Monday, told IANS.
The "Jism 2" actress has denied that the rape statement attributed to her by Kamaal on micro-blogging site Twitter was made by her.
On Jan 31, Kamaal had mentioned on his Twitter timeline that Sunny had said something to this effect.
"In normal cases, I would have ignored this man's tweet. But it became an issue and I am not insensitive. Being a woman, I am not one to make a loose comment on rape. At a time when the country is in the aftermath of what happened in New Delhi, it is disgusting for someone to make a joke out of this," she said.
"I strongly condemn the man's incorrect and insensitive statement and his false accusation of me having made a callous remark like that," added the actress, who is busy working on "Ragini MMS 2".
Sunny and Kamaal have a common string - their claim to fame in India is reality show "Bigg Boss".
The actress is said to have been offered a project by Kamaal earlier.
"I was informed by my manager and husband (Daniel Weber) that this man had earlier offered me a film. We had refused. Maybe this is his way of getting back at us," said Sunny.
