Artists are usually looked upon and idealized...when u're a fan and u hear u're "hero/heroine" make a fool out of themselves u're let down. Scandals are eye-openers into their personalities...no affect on their fan-following.
Artists are usually role-models..and when u're role model drops and stoops to a different level, u wud suffer from shock!
Many of Abid Ali's fan's no longer respect him for him marrying Rabia.. and when he openly said on tv that "I was never a good father or husband" he lost more... they don't doubt his acting skills still.
