'Ki and Ka' star Arjun Kapoor's prank on Bollywood superstar Kareena Kapoor Khan ended up with the actress running for cover and refusing to shoot

Kareena Kapoor suffers from Katsaridaphobia, a fear of cockroaches.

In a bid to overcome her fear, her 'Ki aur Ka' co-star, Arjun Kapoor, opened a jar full of cockroaches in her presence on the set of his reality show, 'Khatron Ke Khiladi'.

Bebo made a quick dash and refused to shoot till the crawlies were taken out of her sight.
