Kareena Kapoor gave brilliant performance in 'Chameli'. Director Sanjay Leela Bhansali left for Shimla for the first shooting of 'Black'. Shimla thinks he has come to shoot for 'Bajirao Mastani'. "I always had full faith in Kareena, otherwise I wouldn't have signed her for my Bajirao Mastani. Her performance in Chameli only strengthens my belief that she's the best we've today, and the only truly classic actress since the generation that went by after Madhubala and Meena Kumari." He is very much confident of his choice.
