Bipasha Basu is worried as her boyfriend John Abraham is now shooting in the Taliban-infested area for Kabir Khan's 'Kabul Express'. Bipasha and John's mother have decided not to allow him take such a decision again in life. She said, "I wouldn't have been so concerned if he was there to shoot a documentary. He'd have finished his work soon then...but 45 days in a long time. And John has not been keeping too well. The weather there is -1 degree and I am not sure about the kind of food he is eating. He has been telling us that the security has been very tight but I am still worried."
