It looks like the seemingly never-say-die friendship between director Siddhartha Anand and Saif Ali Khan is for all practical purposes, over.After their two films together Salaam Namaste and Tara Rum Pam Pam the two had sworn to work together again… and again.But Tara Rum Pum didn’t do well. And Sidhartha quickly gravitated towards his childhood buddy Ranbir Kapoor for his next film Bachna Ae Haseenon.It was widely believed that Saif would be back in Sid Anand’s next which he is committed to make for producer Sajid Nadiadwala.But the producer confirms that Ranbir is the lead in the film that Sid Anand is making for Nadiadwala.The surprising bit of casting is the hot-and-happening Priyanka Chopra. Though neither producer nor director are willing to confirm, according to dependable sources Priyanka who’s currently shooting with Uday Chopra for Yashraj Films Pyar Impossible will be teamed up with Priyanka for the first time.The actress has lately been window-shopping for the hottest male actors in Bollywood and has so far managed films with all the three Khan superstars, several projects with Abhishek Bachchan Akshay Kumar and Hrithik Roshan, has just completed Kaminey with Shahid Kapoor and is now on to the new generation of stars with Ranbir leading the bright pack.The pairing spree certainly gives Priyanka an edge over her rivals.Siddhartha Anand describes the Ranbir-Priyanka film as, “A rom-com which I’ve specialized in over the years. But this is a twisted one with a twang and all that jazz.” .
