Deepika also praised "Queen" director Vikas Bahl for portraying a woman's emotions so beautifully.
"What a beautiful film. I think if you are a woman and have been in a relationship, just the way he has captured the emotion of the girl and the way he has portrayed it, it's one of the best films I have seen in the longest time and it's outstanding," Deepika said.
"Queen" hit theatres March 7 and is getting rave reviews from both critics and audiences. It also stars Rajkummar Rao and tells the story of a girl who goes for her honeymoon alone and captures her journey of self-discovery.
