Singer Mangli on Wednesday apologised after the song 'Sarke Chunar Teri Sarke' from 'KD: The Devil' faced backlash. The track, featuring Nora Fatehi and Sanjay Dutt, was criticised over vulgar and offensive lyrics. "I sincerely apologise to each and every one of you for...unintended mistake. It was never meant to hurt anyone's sentiments...and we truly regret the oversight," she wrote.
