There is something about this girl which makes her different from other actresses. Whether it is her straight forward answers or her cool attitude, ahe slays everytime.
Now coming to your question, yeah absolutely she is much more confident then her contemporary Janhvi Kapoor.
She grew older with a single parent. Obviously she had her father’s support still she faced all the challenges that came through her way, learn from them and come forward as the girl next door image with whom most people can relate to.
Her mother Amrita Singh herself is quite confident and strong lady who taught her daughter the same things.
Another thing that maker her look confident is that she doesn't gives a dammn about what people think of others or how she is being judged. She does whatever her heart says to do without much caring about people.
Also she prooved her strong determination by reducing a quite number of pounds and groomed herself well to enter in the industry.
Now talking about Jhanvi Kapoor, she is a pampered child who is always protected by her family and her close ones. She thinks according to them, works according to them and when the end result is not good she becomes nervous. She is too much dependent on other people in her life that she never have given her piece of mind on anything.
Jhanvi needs to work very hard on everything if she wants to survive in this industry for long.
And Sara.. Keep slaying girl :)
