As SS Music earlier reported there were rumors that Lakshmi Menon had done a lip-lock with Vishal for Naan Sigappu Manithan. A Source close to the film unit have now confirmed the rumors
"It's true that director Thiru recently shot a kissing scene with Vishal and Lakshmi Menon. It is a love scene that has been aesthetically filmed. It was a very quick shot and was completed in a single take. Though Lakshmi Menon was initially reluctant, she understood that the story demanded such a scene and went ahead. The scene is very crucial and will play a key role in what happens to Vishal's character in the film."
Apparently, the director ensured that both the actors were comfortable with the notion before going ahead to shoot it. Sources also add that the makers have ensured that the kissing scene has not been forced into the movie but rather an integral one, like the kissing scenes in Vinnaithaandi Varuvaaya.
