The 36 China Town star accused the filmmaker of being hypocritical on her Twitter account, for opting to work with Leone in Murder 3.
"Heard Mahesh Bhatt signed the porn star in Bigg Boss. And he was talking about not being hypocrite. Hope indian audiences like this (sic)," posted Rohatgi.
The Corporate actor, who had competed in an earlier series of the Indian format of Big Brother, added that producers were manipulating its content.
"Bigg Boss 5 is changing its rules accordingly to its own whims. So now I think its getting scripted as they change their rules for TRPs," she said.
In March, Rohatgi said that director Dibakar Banerjee had attempted to sexually harass her during a meeting to discuss a film role.
The actor-turned-reality television show star will be seen next in the upcoming series of Survivor on Indian TV.
