Rekha & Amitabh Bachchan

Ok, so we all know about how back in the day Rekha and Amitabh had a thing, right? But whenever you ask these two they always vehemently deny everything and anything and say it's all media created. If it is all media created then could somebody please answer these questions:

1) Why haven't they worked in a movie together since 1981, Silsla?(They have appeared in the same movies after this but they did not have any scenes together and one or the other always did a guest appearance.)

2) Why do they avoid each other at all functions or public places?

One of the most talked about moments of the night. Why couldn't Amitabh just sit there and say hello. The release of Sarkar, complety ignores her presence. Amitabh should at laest pose properly for the picture, we can see you are together you idiot!

3) Why are they always in a hurry to end a question where the other person's name arises?
Honest to god it really makes me mad when they do this because they should at least have the guts to say that they had a relationship together and now its over, why are they so reluctant to do this?

Look at how close they are to eachother! I don't think Amitabh has taken such pictures with any other actress, not even his wife!

Amitabh made it very apparent at the recent Filmfare awards that he did not want anything to do with her, when he walked away when she came over to say hi. Like its so bad between these two that they can't even say hello? Man this makes me mad!
