Well, the reason for that is the young tiger's bloating shape. As such, NTR looked lean and fit as a fiddle during the times of 'Yamadonga' and 'Kantri' but in no time he began to put on weight. Currently, Junior is gearing up to arrive with his film 'Dammu' and many Nandamuri fans are slightly concerned about his shape.
However, a source close to the actor mentioned "There is nothing to worry. NTR is fully aware of his body condition and he is maintaining it like that to get the required impact for his role in 'Dammu'. He should be back to his original frame once 'Dammu' is complete."
