New Delhi: Actress Jacqueline Fernandez says donning a judge's hat for dance reality show "Jhalak Dikhhla Jaa 9" is a "big responsibility" for her. The Sri Lankan beauty will be joined on the judges' panel by filmmaker Karan Johar and ace choreographer Ganesh Hegde. Talking about it, she said here: "It's a very new and different experience for me. I have amazing co-judges with me and we're having a lot of fun. It's quite a big responsibility judging these contestants who are big celebrities." The Colors show, which will go on air on July 30, will feature actors Sidhanth Gupta, Shantanu Maheswari, Surveen Chawla, Karishma Tanna, Helly Shah and Shakti Arora among others as contestants. Jacqueline was in the capital for a press conference of her forthcoming film "Dishoom" here on Monday. The "Kick" actress was joined at the event by her co-stars Varun Dhawan and John Abraham. Talking about her role in "Dishoom", Jacqueline said: "It's actually a tomboy character. It was a lot of fun because I actually got to do what the boys were doing -- the action and all the running around. I was really excited to play this character of Ishita." Directed by Rohit Dhawan, "Dishoom" is slated to release on Friday.
