After creating Box Office history with ex-girlfriend Deepika Padukone in 'Yeh Jawaani Hain Deewani', rumours mills are suggesting that Ranbir Kapoor may be paired with the actress again in director Imtiaz Ali's next. They teamed up after a gap of five years (the last time being the 2008 'Bachna Ae Haseeno') for 'Yeh Jawaani Hai Deewani' (YJHD) and they managed to hit the bullseye. The talk of the town is their unmistakable chemistry. The ex-lovers painted the town red even during their promotional tours and their affection was visible. As Ayan Mukerji’s latest hit continues to rake in money at the box office, it hardly comes as a surprise that filmmakers want to cast the duo together again. Imtiaz Ali, who has already worked with Ranbir in 'Rockstar', is set to cast the actor once again. But the director is in dilemma over the female lead and has been unable to confirm any name. The yet-untitled project will be produced by Sajid Nadiadwala. It is rumoured that after watching the two in YJHD Imtiaz has decided to bring back the currently hot pair for the role.While talking to reporters during the launch of new pair of spectacles in Mumbai Deepika said, "I would love to be a part of the film but I haven't heard from them. I dont know what is happening."

The actress said, "I can't pick up the phone and call them. I would rather want them to believe that I'm fit for the part and pick up the phone and tell me themselves." Deepika, of course, is known to share a great equation with the director, whom she worked with in 'Love Aaj Kal' (2009). Interestingly, Katrina Kaif has also been eyeing for the role opposite rumoured boyfriend Ranbir Kapoor. She has sent fillers to the director and shown her keen interest. It would be interesting to see Ranbir's stand in the whole equation between his ex and present girlfriend. But he doesn't seem to be making any visible effort to recreate his 'Ajab Prem Ki Gazab Kahaani' with Katrina on-screen. After all the Ranbir of 'Ajab Prem Ki Gazab Kahaani' is a far cry from the Bollywood heavy weight Ranbir is today and perhaps Katrina will find it difficult to match Ranbir's eccentric choice of movies. Whereas, Deepika seems to have taken cues from ex-beau about evolving and has quite a few meaty roles to her credit. And hence it is natural that Ranbir might rather act with Deepika than girlfriend Katrina. However professional pairing or not, if Katrina manages to win over Ranbir completely off-screen that will be a happily ever-after for the actress. And this possibly is the only starring role Katrina is interested in.
