Mega Power Star Pawan Kalyan who is busy shooting his upcoming action-drama under Sagar Chandra's direction has paid a surprise visit to Rajamouli's RRR sets. Pawan had a small chit-chat with director Rajamouli. The shooting of both RRR and Pawan's Ayyappanum Koshiyum remake is currently in full swing at Aluminium factory in Hyderabad. However, this surprise visit of Pawan also made some rumour mongers cook stories of a possible collaboration with Rajamouli in the coming days. But both Pawan and Rajamouli are busy with a few films in their kitty.
