She said that in the promos, she can be seen as a "happy" and "bubbly" girl, "but in the film I am playing a completely different person".
"I am a very sensible and sorted human being, probably more sorted than the other two (characters - played by Sushant Singh Rajput and Vaani Kapoor) with me. Very quiet, so you will see a new side of me," added the 24-year-old.
She divulged details about her character while promoting 'Shuddh Desi Romance' along with her co-stars at a college here.
Parineeti also revealed that her cousin and actress Priyanka Chopra is eager to watch the film.
"Yes, my sister watched it (promos) and she really loved it. She is waiting for me to have a trial and we have also not seen the film yet. So, she is totally supportive," she said.
Directed by Maneesh Sharma, 'Shuddh Desi Romance' marks the debut of Vaani Kapoor.
