Even as actors Salman Khan and Katrina Kaif have parted ways, they still have been “good friends”. So much so that even after their break off they could not stop gushing about each other.But is their friendship real, or is it just a tactic to create buzz about their upcoming film Ek Tha Tiger?As Salman was presented an expensive sports utility vehicle (SUV) by automobile company Audi for using its products in his last blockbuster Bodyguard, he said, “Very beautiful car… Katrina drives this car.”Do Salman and Katrina still miss each other? If not then why do they keep talking about each other even after their love story became a thing of past?It was not the first time when Salman had spoken fondly about his “friend”. Ever since the two started working on their upcoming film, Ek Tha Tiger they have been painting the town red with the tales of their friendship.”Katrina is a very good friend. We are doing a film together. She is a great girl,” he had said earlier.In a recent interview to a fashion magazine, Katrina had said: “Salman was my first serious relationship.”That really leaves one wondering if this off-screen chemistry was for real or just a publicity strategy for Ek Tha Tiger.
