Even before NTR's song from Nannaku Prematho was on the chartbusters, the Young Tiger had crooned for Puneeth Rajkumar for the film Chakravyuha in December

The video of NTR rendering the song with Puneeth and SS Thaman became an instant hit as soon as it was released on Internet. The latest one to join NTR and Puneeth is Kajal Aggarwal. She has sung a duet along with Puneeth weeks after NTR's tryst with singing in Kannada.

NTR's song will be awaited by his fans, so also Kajal's number. Puneeth has always shared a friendly relationship with NTR. Kajal's entry, however, makes one wonder if there is some connection to the story which is why two stars from other industries have been 'imported' to croon two songs.
