Singer Sonu Nigam broke down in tears while singing 'Mere Dholna 3.0' during his Bengaluru concert on Sunday. He later shared a video on Instagram, expressing how emotional he felt during the performance. Nigam said he used to cry in a similar way when his mother passed away in 2013, adding he'd sing 'Kya Hua Tera Waada' and 'cry uncontrollably'.
