Tollywood singer Kaala Bhairava who performed live on the Oscars stage for 'Naatu Naatu', expressed regret for failing to acknowledge Ram Charan and Jr NTR after his Oscar win and apologized to their fans. The singer took to his Twitter handle and clarified that he had no intention of disregarding the two actors, who he believes were instrumental in the success of both 'Naatu Naatu' and 'RRR'. He explained that he was only referring to those who helped him secure the opportunity to perform on the Academy stage and nothing else. He tweeted as "I have no doubt Tarak anna and Charan anna are the reason for the success of naatu naatu and RRR itself. I was ONLY talking about who all helped me get my opportunity for the academy stage performance. Nothing else. I can see that it was conveyed wrongly and for that, I sincerely apologise for my choice of words."
