"I am not over-confident but quite confident and excited about the film," she said at a promotional event, marking the film's tie-up with clothing brand, Jealous 21, here.
Asked about she is jealous of in life, she said: "I am jealous of people who get to go on holidays, even though I go on many on my own. I love travelling. I am also jealous of people who get to eat whatever they want."
"The first film is always special. That innocence never comes back. 'Refugee' is my favourite film," she said.
"Heroine" revolves around the ups and downs in a journey of an actress. Kareena said that even though she is playing the role of an actress in the movie as well, she is nothing like that in real life.
"People think there are similarities, but I am not like that in real life. She is bold, manipulative, dark and edgy. I am not at all like that," she said.
Talking about her look in the film, she said: "My favourite looks are in the title song of the film, which is yet to release."
