Sara Khan
She is famous for her role in Bidaai as Sadhana, so people love her and thus she became a household name but with fame and money coming to her she is now known for her starry tantrums which she gives either to the media or dance reality show (production house).So we hate her for her airy behaviour.
Angad Hasija
Better known as Alekh of Bidaai, he is a very fine actor and that gave him a huge fan following especially female fans for his role in Bidaai, but the shocking news which he gave to the world was that he is married and he has a one and half year old daughter. He hid his marital status, so we hate him.
