The Canadian former porn actress has made her Bollywood debut in Jism 2.
She told The Times of India: "I saw Ekta [Kapoor]'s The Dirty Picture and was mesmerised by it. I don't think the word 'fat' fits in my dictionary, but to carry off that look, and glamorously so, is a big feat. Hats off to Vidya for that, I'm almost jealous!"
The Dirty Picture is a biopic of the late famous southern actress Silk Smitha, who was known for her onscreen nudity.
Leone has said that she will be focusing only on mainstream Indian cinema for the next two years.
She joked last week that she found the public controversy over the film and its publicity "flattering".
Posters featuring the bare back of a body double for Leone have been torn down from hoardings following complaints from a nationalist politician.
