Bipasha Basu, who is busy promoting her next Raaz 3, suffered from exhaustion while filming the film.
She plays an emotionally scarred character in the film and that drained her so much that she was sleep deprived. Her exhaustion led to a weight loss of 3 kgs.
Bips was not following her diet properly. She lost her appetite and her sleep while shooting for the film.
To rejuvenate herself, Bips took a holiday to Goa after she wrapped up the film.
