Sony Entertainment Television’s popular singing reality show Indian Idol Junior host Karan Wahi is again up to his usual funny antics on the upcoming gala episode. The hilarious host pulled a successful prank on judge Shreya Ghoshal which had her petrified. A gush of horror spread across the set of Indian Idol Junior when Priyam sang Gumnaam hai koi. Not only did the song spook the audiences and the judges but it gave rise to an evil thought in host Karan Wahi’s mind. As soon as Priyam’s performance ended, from nowhere Karan sprang up from behind Shreya’s chair sporting a scary mask. The beautiful singer got the scare of her life and was left terrified. After catching her breath she slyly joked about what happened and also appreciated Karan’s acting skills. The sequence will air this weekend!!!
