Like his close friend Shruthi Haasan, Siddharth too is a multi-faceted personality, we must say. The actor, who had earlier crooned 'Adada Adada...' in 'Santosh Subramanyam', is at it again. He has lent his voice for his good friend and 'Boys' co-star Thaman.

Siddharth is playing the lead role in 'Kadhalil Sodhappuvadhu Eppadi', a movie directed by debutant Balaji, who hogged the limelight with a talent hunt for aspiring filmmakers on a television channel. And music for the bilingual (Tamil-Telugu) is by Thaman, who is now a top composer in Tollywood.

Thrilled about working with Siddharth in a Kollywood venture after 'Boys', Thaman wanted his pal to sing an interesting number in 'Kadhalil Sodhappuvadhu Eppadi'. The actor, who was happy to accept the offer, crooned it like a seasoned singer, sources in the know say.

"Working with an old friend on the new film. Hotshot music composer Thaman," Siddharth, who is sharing the screen space with Amala Paul in this film, expressed happiness on his micro-blogging page.
