The controversial actress competed against Upadhyay in the Indian version of Big Brother.
He told The Times of India: "Bringing her in a family show like Bigg Boss doesn't augur well for Indian culture. Just read the 250-plus comments that have been posted on the Bigg Boss's website on that particular episode of Sunny and me.
"Women have openly blasted her for making false accusations against me. She is ruining the psyche of 12-year-old boys in India, who are now doing google search on her after reading about her pornographic escapades and seeing her on telly."
Upadhyay added: "Hindi film producers should think 100 times before considering Sunny. Tomorrow she may accuse them of sexual harassment for shaking hands with her! She only wants publicity."
Leone will make her Bollywood debut in the sequel to action thriller Jism.
It was reported last week that the rumoured porn star will be seen nude in the opening scene of the film.
Director Mahesh Bhatt said that he chose Leone over more established stars such as Bipasha Basu because her real life story would "resonate" with viewers.
