Chennai, March 14

Southern actress Lakshmi Menon couldn't attend the audio launch of her upcoming Tamil thriller "Naan Sigappu Manithan" Thursday because she was busy writing her Class 12 exams in Kerala, says actor Vishal Krishna.

This is the second time in a row Vishal and Lakshmi have worked together after Tamil drama "Pandiya Naadu".

"She wanted to be part of the audio launch but she couldn't make it because of her exams. She's writing her Class 12 exams in her hometown (Kerala). She will join us soon for the promotions of the film," Vishal told IANS.

Vishal-starrer "Naan Sigappu Manithan", which is about a character suffering from narcolepsy, is slated to release April 11.

Directed by Thiru, the film is jointly produced by Disney UTV and Vishal Film Factory.
