And it is official! 'Kalasala...' from Simbu's forthcoming 'Osthi' is already much-expected by fans who are eagerly looking forward to the audio launch on October 6. This track is an item number featuring Simbu, Sonu Sood and Mallika Sherawat and its original, 'Munni Badnam Hui...' from 'Dabangg' was a smashing hit.

It was earlier widely speculated that Shruti Haasan will croon this song, however, sources close to the unit had rubbished that and revealed that a voice that will set a rage among rural and urban masses will croon this peppy number and guesses were made on who will sing this track. It is now official that LR Easwari along with T Rajendar have lent their voices for 'Kalasala...'!

Not just that, those who have heard the number vouch that it will be the song of the year throughout TN. The songs for 'Osthi' have been composed by Thaman.

Are you all ready to go 'Kalasalla...' in a few days?
