"Working with Kareena is one of my most cherished memories. She has been a darling. Sometimes you just click with certain people instantly and that's what happened between Kareena and me," Delnaz told in an interview.
"We talked about everything. We bonded over everything. She is very supportive. You'll see that our on-screen chemistry is great and that is only because of our off-screen chemistry," she added.
There was also another connect for the two Virgo gals food. Kareena turned vegetarian during the making of this film and Delnaaz emulated her. "My next goal is to follow Kareena all the way till size zero, " she says.

In "Milenge Milenge", she is playing the role of Honey, which she calls an extension of Sweetu. "My character in the film is that of a very close friend of Kareena. She is a chirpy, vivacious person, an extension of Sweetu.

The film, slated for release July 9, also stars Shahid Kapoor and is directed by Satish Kaushik. The film is releasing five years after getting into production.
When asked whether she was still in touch with Kareena, Delnaz responded: "We have not been in constant touch after the shoot got over. But I did meet her eight or nine months ago at an awards function.
"The media was hounding her at the event. Suddenly she saw my husband Rajeev at a distance and shouted, 'Rajeev, where is Delu?' I felt really nice that day because I realised that she is such a grounded person," Delnaz says with admiration.
And what about Shahid, who is also a part of the film?
"Shahid is a great person and a very meticulous actor. He is always ready to improve his performance. After every shot, he used to go and watch his performance on the screen so he could improve wherever required," she said.
"In that sense, Kareena is more spontaneous, she is a livewire," Delnaz added.
