Actress Kajol has completed '27 years of being a killer full-time' as her nerve-chilling thriller 'Gupt' turned a year older on Friday. Commemorating 27 years of the film's release, Kajol shared two throwback photos from 'Gupt'. While the first one was a solo still of the actress with spooky expressions, the second showed her hugging her co-star Bobby Deol.
