The divorce of the celebrities might be due to their nature of job. The long shooting hours, outdoor shooting does not allow them to spare time for each other. They cannot understand each other resulting confused relation. Again the excessive interference of media in their personal life and the spicy gossip created by them might worsen the relationship.
Most of them are love marriages and it has happened only after proper understanding. Then why can't they understand the character of job :P .
Let me tell you tragic history of 3 actor sisters of our industry. Kalaranjini, Kalpana and Urvasi, of which Urvasi is my most favourite Malayalam heroine. Kalpani is my most favourite comedy actress. Kalaranjini, is not that much successful as other two.
Urvasi married her co-star Manoj.K.Jayan years before(love marriage). I don't know much about Kala. Kalpana married a director, love marriage.
The biggest tragedy is that all three are divorced now. They lost their younger brother some years before. Totally, a tragedy.
A couple of years back, a film came about 3 separated friends. It came true for these 3 celebrity sisters
