Why is Balayya absent from Charan’s marriage?

Nandamuri Balakrishna’s absence from Charan’s marriage had given scope for several murmurs. Did the traditional rivalry between the two families got to do some thing with the absence?
No say our sources. According to our sources, Balakrishna had flown to Switzerland today at early morning hours from Hyderabad. Two songs of the movie will be shot there and he will fly to USA from there. He will be attending the NATA convention at Atlanta. He will be also conducting few fund raising events for Basavatarakam Cancer hospital. He will be back again to Hyderabad on 7th of July
