Sonu Nigam, who earlier spoke about the 'music mafia' in Bollywood, has now slammed T-Series chairman Bhushan Kumar for allegedly attempting to sabotage his image. Sharing a video on Instagram, the singer called out Kumar and said that he has messed with the wrong person and now he deserves to be addressed without respect. Sonu further reminded Kumar that he still has the video of Marina Kanwar and if he messes with him again he will upload the video on his YouTube channel.
