Janhvi Kapoor reflected the excitement and nervousness of a Bollywood debutante at the trailer launch of her maiden movie "Dhadak" here on Monday , but she was emotional as she missed her mother , the late Sridevi's presence at the special occasion. The 21-year-old was accompanied by her father , producer Boney Kapoor , who has been her constant support after the sudden demise of Sridevi earlier this year in Dubai.
