Singer Shreya Ghoshal experienced a scary moment on the sets of "Indian Idol Junior", courtesy host Karan Wahi.

Karan was up to his usual funny antics while shooting an upcoming episode.

After young contestant Priyam sang the haunting "Gumnaam hai koi", a nasty prank struck Karan, who sprang up from behind Shreya's chair, sporting a scary mask.

Shreya 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.

"Indian Idol Junior" airs on Sony Entertainment Channel.
