Is her choreographer the reason behind Drashti Dhami's break up?

The buzz suggests that Neeraj was not too pleased with Drashti and Salman's on-screen chemistry in a dance show. However, a friend of Salman says, "People are speculating because they are partners in Jhalak Dikhhla Jaa. However the real reason is something else and Salman has nothing to do with it."
