Sonakshi was joined at the event by director Milan Luthria, who is working with her in the sequel to Once Upon A Time in Mumbaai.
In the movie, Sonakshi features opposite Akshay Kumar, who plays don Shoaib Khan. But she refuses to call her own part negative.
"It's negative? No. It's a very interesting character. For me, as an actor it is a very challenging role and the film is set in a very interesting premise. It is a great role, that's all I can say now," Sonakshi said.
The film also features Imran Khan and Sonali Bendre. It is to release around Eid next year.
