The actress will be seen with My Name Is Khan co-star Shah Rukh Khan in Karan Johar's Student of the Year.
She told The Times of India: "Getting married and still doing movies? Seriously, I don't think I'm a pioneer in that field. My mother did it. All of them... be it Sharmila Tagore, Zeenat Aman, Saira Banu.
"So many actresses out there have done it very well. It's a perception that people have and to a certain extent, that may be true. It gets restrictive."
She continued: "Like after marriage, I would not have been able to do a teeny bopper movie. But I was fine with that. I was not in that space where I wanted to play a college girl. I have never ever regretted anything. In life, I take my decisions and stand by them. Some decisions may have proven to be not the best, but I have learnt from them and I've never repeated a mistake again.
"If someone tells me to turn left, I will go right! I could not have been taught a lesson in any other way rather than by going through it. But it's all my experiences that have contributed to making me what I am today."
