Katrina Kaif engages in some fun with co-star Hrithik Roshan on the sets of 'Bang Bang'

Katrina Kaif seems to be in a playful mood on the sets of Siddharth Anand's film in Similan Islands, Thailand


She insisted on giving co-star Hrithik Roshan a pair of horns. Aren't such naughty things done by school kids? Guess the child in Kat is still alive. Their film together is a remake of the Hollywood flick Knight and Day which starred Tom Cruise and Cameron Diaz.
