"I did the film because I think Prasoon Joshi wrote the most incredible script that I have ever read. I was crying while I was reading it," Sonam told PTI.
"I don't have a big role in the film; it is really a small role. I wanted to work with Rakeysh Omprakash Mehra (director), he makes me feel beautiful. I wanted to work with Farhan Akhtar," the 28-year-old actress said.
Sonam revealed that she is a big fan of the multi-talented Farhan, who has displayed his versatility as an actor, director, producer and singer.
"When I got the opportunity to work with him, I was more than happy. Even if it's a small chance, to share a small frame with him, even if he does not direct me or works with me again, I can tell everyone I worked with Farhan. I did 20 days of work with him and it was very cool," she said.
Sonam said she was fine with being a small part of a very good film rather than doing a not so good film.
