Keeravani sparks controversy about Hindi singer

Looks like MM Keeravani is very much interested in taking pot shots at others.  Recently, he came down harshly on Tollywood's contemporary directors.  As an old-timer, he is bound to have stronger convictions than the rest of them.  Thus, being frank (or harsh) comes as a natural progression for him on social media.  

In his latest tweet, Keeravani said that a famous Hindi singer felt offended when he (or was it she?) was offered a song for the Malayalam version.  MM said this in the context of re-tweeting RGV's tweet: "The Biggest Hindi film,The Biggest Tamil Film, The Biggest Kannada Film,The Biggest Malayalam Film is nothing but a Dubbed Telugu Film".

Since he hasn't named the singer, his followers have started making speculations.  From Khailash Kher to Daler Mehendi and Shankar Mahadevan, wild guesses abound.  

Let's see if Keeravani names the singer who felt it would be insulting for him to sing a song for the Malayalam version.
