Actor Imran Khan is not just smitten by the beauty of Katrina Kaif, but by her hardwork and dedication too, after working with her in "Mere Brother Ki Dulhan".

"I think this film will do very good things for her. We have often heard that she is just a pretty face and she can't act. But with this film, Katrina is going to prove all of them wrong, " Imran told.

"Mere Brother Ki Dulhan" is a romantic comedy from the Yash Raj Films stable, and Imran says he enjoyed working on it.

"It was fun working with Katrina. I was very impressed with her. She is an incredibly hard working girl. For someone who hasn't known the language (Hindi), the way she has worked on that and the way she delivers her dialogues now is incredible, " Imran said.
