Ash backed out of 'Dostana' because she didn't want to play love interest of two guys in the same film when one is her husband. Also for most part of the movie it is Abhi and John trying to show everyone that they are gay couple. So Ash would have been a misfit as it is not easy to wipe Abhi-Ash real life status from Indian audience's mind.
The movie is an inspired😛 version of 'I now pronounce you chuck and larry'.
BTW here's KJo and John shooting for Dostana.
