Nag Following Late Ntr?

Late NTR was proved to be legend as he acted in many mythological roles and received wonderful applause then.  Whenever, he acted in any devotional or god's get up, he would undergo diet control. Also, he would eat vegetarian food only. 

It seems, King Nagarjuna is also following the same measures when late NTR, used to follow them while doing mythological roles. As per the grapevine, it is learnt that Nagarjuna is not taking non-vegetarian food in his diet as he is doing the role of Saibaba in 'Shirdi Sai' movie. Also, he is said to have renounced glamorous outfits and fashion wears temporarily. This movie is being directed by K.Raghavendra Rao. Keeravani is rendering the music. Nag's fans are expecting that this film is going to be a big hit like other devotional flicks of Nagarjuna like, 'Annamayya' and 'Sri Ramadasu'.
