Katrina Kaif had much to thank the chivalrous Ali for as he rushed to her rescue when her hair got stuck in a fan in between a shot.
Explains a production source, "When Katrina finished her shot she stood near a fan when all of a sudden her hair got caught in its blades. Luckily Ali Zafar noticed it and rushed to help her before her entire hairdo was tugged into its blades. Thanks to Ali's quick thinking Katrina was saved from a major disaster. Katrina thanked him profusely the entire day."
