The singer was finally convinced to make her acting debut by director Nikhil Advani, but says that she often jumbled up her dialogues and had a tough time remembering them.
"When Nikhil called me and said that he is offering me a role in his film, I could not stop laughing and asked him several times if he was sure about it. I had to give a screen test and I was nervous because I can remember lyrics but not dialogues," Kaur told media.
"Nikhil believed that I could do justice to the character and I am thankful to him," she said.
The singer-turned-actress will sport a de-glam look in the movie contrary to her hip-hop style.
"I play the role of Komal, who is Akshay`s cousin. She is a very simple girl wearing salwar-kameez and `lambi choti`. In the film I want to be a rapper but I am afraid of what will happen if Rishiji comes to know about it. Without his knowledge, I try to fulfill my desires," she said.
And the `Glassy` hitmaker says that she was able to connect to her character because of her Punjabi roots.
"I was able to connect with my role because as a Punjabi girl, when I was a child my relatives used to tell me that girls of the family should not sing, dance and all," Kaur said.
The 31-year-old, who had earlier participated in the TV dance reality show `Jhalak Dikhla Jaa`, had received a couple of film offers earlier but did not want to do stereotypical roles.
