Priyanka Chopra and director Rajiv Rai are working together in 'Asambhav'. The interesting news is that they both share the same bithday - 18th July. Rajiv says, "We celebrated our birthday together last year. But this year we have no time to celebrate." He adds, "I am not much into zodiac signs. So I don't know how much of a Cancerian I am or am not. But Priyanka and I get along very well. I don't know if that has anything to do with her being a Cancerian, too. We are not very similar. The only common thing between us is Asambhav and our birthdays."
