Filmmaker Indrajit Lankesh says actress Sunny Leone, who will be seen in a cameo in his forthcoming Kannada film `Luv U Alia`, has a `great work ethic` and he enjoyed working with the sultry siren.

`It has been an absolute delight working with Sunny. She has great work ethic. Originally we had decided to do four changes for the song 'Kamakshi'. But working with Sunny turned out to be so smooth that we were running ahead of schedule,` Lankesh said in a statement.

The director also added that Sunny was "very cooperative" and also gave some valuable suggestions.

"We decided to add a couple of looks and experiment with a couple as well. Sunny was very cooperative and she also gave some valuable suggestion for the looks. She has a keen eye for style and detail,` he added.

Featuring actors Ravichandran and Bhoomika Chawla in lead roles, the romantic drama will feature the `Jism 2` star in an interesting role.

"Luv U Alia" will have its Kannada release on Friday, following which a Hindi-dubbed version of the movie will release across India.
