Yes. That's what we hear that most in the films are from that area. But .. we dont really know the girls on TV are actually THAT GOOD or not.. Havnt you heard stories about them and rumors. :) Yet again job/work cant classify sharif or corrupt person. Insan khud acha ho tu kahin bhi ho doesnt matter.
I know but generalizing is not good. There are women from well respected families on TV too. Just for fun of it.
I know the richest family from my city their girls, used to work in their own ads once in a while. They used to have add on air in summer. They younger cousins were our class fellows. Very gentle reason able ppl. We cant just say every one there is bad.
