Just thought I would clarify. Bobby & Sunny are from Dharmendra's first marriage and Esha & Ahana are Hema Malini's daughters.
They do talk although hema and her daughters live together, separately from the others. In her earlier interviews, Esha explained how she probably got on better with Bobby and their cousin Abhay as they were more outgoing but she was also pretty close to Sunny. She said that everytime Sunny used to come to London for shooting he used to take her back a pair of trainers as they were her favourites.
I think they (especiially the boys) don't talk so much about her in interviews cos they are a really private family - how much do you ever hear abour sunny's wife and kids? and also cos they didn't want Esha to go into films. Dharmendra kept saying she looked too much like a kid, but when Naa tum Jaano na Hum with Hrithik Roshan came out he said she looked like beautiful doll and supported her more.
yeah dats right .. boby and sunny have the same mom and esha and the other gal are from hema malini .. Preety gurl the info you got was wrong .. bobby and sunny ARE real bros
