Nikita Sharma no doubt looks ‘stunning and hot’ as the lead girl Antara in Life OK’s Do Dil... Ek Jaan. However, the same cannot be said of her commitment towards work, is what we get to hear. The girl who moved from Delhi to Mumbai in search of celluloid dreams was ecstatic when she bagged the lead role in this Nautanki Telefilms show. Initially, she was applauded for the efforts she put in to get into the shoes of the Kashmiri belle Antara. However, as time passed by, the production house apparently had some issues with the girl. A little birdie tells us that her lack of commitment and non-serious, too casual an attitude towards work has not been going down well with the makers for some time now. In short, she has failed to perform as per the expectations set by the makers. Nikita has been informed of her short-comings on many an occasions, but nothing seems to be falling in place. All this has prompted the production house to start looking for replacement options for Nikita. Another source from the sets of Jaan tells us that there was indeed a problem with Nikita, but things have been mutually solved between the actor and the makers now. We tried our best to get in touch with Nikita, but could not reach her. All our efforts to get a comment on this from Producer Saurabh Tewari were in vain. Let’s see if the talented Nikita passes this ‘acid test’ and stays on to live the life of Antara on the show!!!
