There was a huge bull and along with it was posing its saviour (Jiah Khan). It seems like after signing Ghajini, Jiah is quite relaxed and has all the free time in the world (as she was spotted in many other events in the past few days).
She signed on the bull stating "Please help the animals, they have feelings too." Jiah seemed to be on top of the world at that time and the happiness visible on her face. Looks like, she is a true animal lover (especially her best friend, The Bull).
