NTR on Dookudu

There has been a cold war going on between Dookudu and Oosaravelli movies, which every movie fan is aware of. There are loads of statements being made claiming that they have created history in Tollywood. However, there is no personal rivalry between the heroes it seems.

Jr. NTR said that he has no rivalry with Mahesh Babu in an interview. When asked about whether he watched Dookudu, he told that he had no time to do that because he has been busy with Oosaravelli promotions and other works. 

Did he call Mahesh to congratulate him?
NTR said that he couldn't call upon him for the same reason. He didn't find time to focus on other things except for Oosaravelli. Needless to ask Mahesh about the same because he is double busy with The Businessman that he couldn't find enough time to promote Dookudu too let alone congratulating NTR on Oosaravelli success.
