Dia Mirza has rubbished rumours that she has signed the dotted line for a Kannada film.

"I'm curious to know who are and how have the makers of a south film made assumptions that I am doing a film with them? False news," the actor-producer posted in a tweet Monday.

There was news that film producer Suresh Babu had confirmed that Dia has given her consent for a Kannada movie titled "Bham Bham Bholenath".
