Also, Ram Charan being a part of RRR and Chiranjeevi starting his 152nd film, became part of happy news that the family decided to enjoy on Sankranthi.
As an extended family, we never saw them assemble at one place all these years, even though they have been meeting at other parties.
This Sankranthi, made all of them, with elder generation to Chiranjeevi to their children to their children's children to assemble as one extended family.
You can see them all including Allu Aravind family relatives in this pic. Only missing person from this huge family gathering is Pawan Kalyan, as you have guessed already.
