Idhu Kathirvelan Kaadhal (IKK) is an upcoming rom-com being directed by SR Prabhakaran, featuring Udhayanidhi and Nayanthara in the lead roles. The latest addition to the cast is Chaya Singh, of Thiruda Thirudi fame, who will play Udhayanidhi's sister in the film.

Excited Chaya Singh says,"The whole package — my characterization, the cast including Udhay and Nayanthara and director Prabhakaran — appealed to me, and I gladly got on board. I play Udhay's sister in the film, and the character's got a lot of depth. I will begin shooting for my scenes from next week in Chennai."

The actress believes that this is a big ticket for her re-entry into Kollywood and is happy to be associated in a film, in which everyone have proved their worth and established themselves as bankable artists and technicians in the industry.

IKK shoot went on floors yesterday in Chennai, which will last for 15 days.
