Directed by Raj Nidimoru and Krishna DK, "Happy Ending" features Saif and Ileana as the lead pair.
"I am working with Saif and it was not a conscious decision to work with a Khan. It just happened. I read the script and I liked it. I am having lots of fun on sets with Saif. It's so much fun to work with Saif," Ileana said in a group interview.
"It's not even like I am working. It's fun on the sets. We have finished a lot of the shooting," she added.
Before venturing into Hindi films, Ileana worked in the southern film industry. She hasn't signed any new project down south, but asserts that she will never quit it.
She said: "I don't think you can ever leave the southern film industry, it's such a colourful film industry. It's very prominent. Right now I haven't signed anything if I have something coming up I will do it. I would not leave that industry."
Her next Hindi movie is `Phata Poster Nikla Hero " with Shahid Kapoor and she calls it a crazy film.
"It's a crazy, mad film. I have never done such a film before. Besides, Rajkumar Santoshi's comic timing is amazing. Nobody can match him," she said.
