Actor Shantanu Maheshwari, who can be seen opposite actress Alia Bhatt in film 'Gangubai Kathiawadi', said that "it was tough for Alia" to slap him during song 'Meri Jaan'. "Alia wasn't able to slap me too hard...we did around 20 takes. She was very sweet...I told her not to bother about it, so she was cool with it," he added.
