I think Vivek done it for own publicity bc'z he had a row of flops so he need publicity and he also want to tell ash that he is only person who can do every thing for her, even he can fight with Mike Tyson for her.
Bhansali takes himself too seriously. One of the prime examples of the hypocrisy that permeates Bollywood, he shouldnt be taken seriously. A lunatic like Salman will have halfwits like Bhansali to support him.
Also, what more can you expect from someone who is like a baniya with a fascination for raunchy colors. It is hard to believe that Khamoshi was the brainchild of someone like Bhansali. Eve harder to digest that morons like Bhansali cnstitute Bollywood's cinematic elite.
