"This girl is very clever and shrewd. She knows how to get who she wants, and she gets him. This is a skill and I hope I also knew how to do it," the 29-year-old said here Wednesday in an interview.
"I always say that Vidya is like an 'imli' (tamarind), a bit sweet and a little sour," she added.
Directed by Abhishek Kapoor, "Kai Po Che!" will see Amrita with Sushant Singh Rajput, Amit Sadh and Raj Kumar Yadav in the cast. It hits theatres Feb 22.
Amrita plays Sushant's sister in the film.
As an actress, Amrita, who made her debut with the 2010-film "Aisha", is sure about the kind of roles she wants to do.
"During 'Aisha' I was new and I didn't know anything, it was a learning experience. I have been in the industry for almost three years now and today I know better about myself and my skills. I am more sure of myself and what I want in life," Amrita said.
