Kangana on the contrary issued a notice through her lawyer citing threat and intimidation on the part of Hrithik.Kangana's lawyer however maintained silence on further developments. He was quoted stating, "I39m not instructed to comment on this. At this stage, I can say nothing. I can neither confirm nor deny the developments. Let something come from Hrithik, and then I can speak."The spat began when Kangana claimed Hrithik as her 'silly ex'. It got uglier when Kangana was replaced by Sonam Kapoor for Aashiqui 3. Adding more fuel to the fire, Hrithik took to a micro-blogging site to deny the affair with Kangana by tweeting, 'Ther r more chances of me having had an affair with d Pope dan any of d Im sure wonderfulwomen d media hs ben naming. Thanks but no thanks sic."
