ew Delhi, July 4(ANI): We have often seen real-life couples being paired onscreen to obtain that extra zing of chemistry. The recent example is ‘Love Story 2050’ which will showcase the real life love birds Priyanka Chopra and Harman Baweja. Next comes the ‘Sarkar Raj’ that brought Abhishek Bachchan and Aishwarya. And to join them in the league are the current heartthrobs Saif Ali Khan and Kareena Kapoor who had costarred in Omkara and now will be seen sharing the silver screen in the flick Tashan.
