Why did Neetu Kapoor have issues with Katrina's family background but does not have with Alia?

We all know Neetu Kapoor and Katrina Kaif did not get along and only for Ranbir's sake they used to talk and attend events. But when it comes to Alia, Neetu seems to be really in fond of her. I mean Alia does not have a good family background like Katrina. Alia's dad, Mahesh Bhatt has gotten into so many controversies and not only him but most of her family members too have some issue or the other. Why do you think she shows this indifference?
