Santhanam irks Kamal Haasan?

Looks like comedy actor who has started doing lead roles in films has annoyed star actor Kamal Haasan. The buzz is that while Ulaganayagan Kamal Haasan was the chief guest at the audio release of Santhanam, Sethu and Vishaka Singh starrer 'Valeba Raja', Santhanam himself wasn't present at the launch and this hasn't gone down well with Kamal.
Santhanam skipped his own movie audio launch since he was busy shooting for Superstar Rajinikanth's Lingaa in Hyderabad.Though everyone knows that the comedian does not attend any public functions, it seemed to have been rude when Santhanam invited Kamal Haasan in person to attend the launch.
