Rishi Kapoor and his wife Neetu had openly shown their displeasure when Sonam and Deepika had ridiculed Ranbir Kapoor on national television, in Karan Johar's chat show. Since then there was awkwardness that existed between the two Kapoor families. However, news has it that things are getting back to normal now.
We now hear that Sonam Kapoor and Rishi Kapoor are getting along quite famously on the sets of their next film. For both of them, water has passed under the bridge and all that is said and done, has already been forgotten.
