Mumbai- They say pointed indifference is the best revenge and Katrina Kaif knows it very well. At a recent Diwali bash thrown by actor Anil Kapoor, Katrina simply looked through ex-beau Ranbir Kapoor, giving him a taste of his own medicine. Since Ranbir-Katrina parted ways early this year, Katrina has apparently tried her best to retrieve their relationship but has got a cold response from Ranbir. Whenever they bumped into each other at mutual friends', Ranbir did not acknowledge the lady's presence. At the recent press screening of ADHM too, Ranbir got Miss Kaif ticked off the guest list. Katrina has obviously decided that enough is enough. At a recent bash, she just swept past Kapoor junior, leaving him high and dry.
