Bollywood director Imatiz Ali's next movie still has to get a name but there is much speculation about which actress will star opposite Ranbir Kapoor in the movie -- is it Deepika Padukone, actor's ex-girl friend, or is it Katrina Kaif, the current girlfriend of the actor. Producer Sajid Nadiadwala, however, is in no hurry to announce the name of his movie's actress.

Media reports suggest that both the actresses are vying for the role and one of them is likely to bag it. Mr Nadiadwala said to The Times of India "No, not true" when asked if Katrina Kaif is starring in the movie.

He was non-committal on Deepika Padukone's name, too and said, "No one has been finalised."

Prior to the release of blockbuster Yeh Jawani Hai Deewani, starring Ranbir and Deepika, there were reports that Katrina's name has been finalised. The onscreen, scintillating chemistry between the ex-lovers may have put a full stop on that as there is a strong media buzz that, makers are keen on exploring the chemistry, again. Also, Deepika is said to be close to Imtiaz Ali as she had starred in his directed movie Love Aaj Kal.

The Times of India reports that Ranbir is keen on working with Katrina. "She hasn't signed the film as yet, but Kat will be doing Imtiaz's film. Ranbir is keen on working with her as well," a source told the newspaper.

Ranbir and Katrina are yet to announce that they are in a relationship but it is no longer a secret that they love spending quality time with each other. They were spotted holidaying in Ibiza, Spain with their friend Ayan Mukherjee, director of Yeh Jawani Hai Deewani. Hindustan Times reports that, "The three (undercover) musketeers were also spotted having a blast at a David Guetta concert in the city." Also, the couple was spotted in Dubai.

Katrina is currently shooting for Dhoom 3 and Bang Bang, while Ranbir, touted as the next superstar of Bollywood, is busy completing Besharam, which due for release in October, 2013.
