Reacting to a 'Twitter war' between Tanhaji and Chhapaak that erupted after Deepika Padukone's visit to Jawarharlal Nehru University (JNU), Ajay Devgn said, "A war is happening?! Who is doing it?" "I feel there is no such war is taking place. People express themselves on social media and we don't take it seriously," the 'Tanhaji' actor added.
