"In terms of my looks in Brothers, it's definitely not a glamourised look. It is very realistic," she told IANS.
"We have to keep it that way because of the type of role that I am playing. We are trying to push the envelope with lot of characters in Brothers. We are going out of the way and being honest to our roles," she added.
The film, also starring actors Akshay Kumar, Sidharth Malhotra and Jackie Shroff in key roles, is produced by Karan Johar and is expected to release on July 31.
Last seen with Salman Khan in Sajid Nadiadwala's Kick, the former Sri Lankan beauty queen has worked with directors like Sajid Khan, Mohit Suri, Abbas-Mastan since her debut in Bollywood with Sujoy Ghosh's 2009 fantasy drama Aladin.
When asked how will Brothers be different from her past films, she said, "In Brothers I am going into a zone that is something that I have not done."
"It's a very simple and desi character. It's also a character that I think a lot of people would not have expected me to do. This is exactly the reason why Karan approached me for this. I think as an actress it is amazing to shock your audiences," she added.
