Kat considers Arjun to be her rakhi brother. Years ago, when they had a common factor (read: Salman Khan) in their lives, the actress is said to have tied a rakhi to Arjun. Aarti is close to several Bollywood folk and in particular to Ranbir Kapoor and his buddy filmmaker, Ayan Mukerji.
Seeing Kat and Arjun together, tongues have started waging. Is there a film in the pipeline? or were the two just hanging out at their common friend's place?
