'Heard of some news that I don't want Bipasha for Munni. In fact I was the one who suggested that she is the best for Munni song, " Sonu posted on micro-blogging site Twitter.
The actor, who plays a villain in the film, gave a clarification following media reports that he is pushing "Sheila ki jawaani" groover Katrina for the song in "Osthi".
Sonu says he is quite keen on Bipasha for the number, which originally featured Malaika Arora Khan.
"Still trying to work around her dates. Have pushed my dates too. If she's on board that will prove all these news to be baseless. She is our first choice, " he added.
Directed by S. Dharani, 'Osthi' will also feature Silambarasan Rajendar, Githan Ramesh and Richa Gangopadhyay.
The movie is set for an October 2011 release.
