The entire Tollywood fraternity came forward for the ‘Memu Saitham’ event to help Hudhud victims. Interestingly, most of the actors greeted each other, but the two actors   continued to share cold vibes. It’s been a year since Nagarjuna and Balakrishna have been avoiding each other at many big events. This time   many thought the two actors would greet each other, but it didn’t happen. In fact, nobody knows what caused the rift between the two, but they stopped talking to each other.  Balakrishna didn’t visit Nagarjuna, when the latter’s father Akkineni Nageswara Rao passed away.
