John Abraham and Bipasha Basu were among the most popular couples of Bollywood. Marriage was definitely the next step for this much-in-love couple. However, their relationship did not mature into a wedlock. Instead, their sudden break-up left most fans shocked. For many, it was John who was not ready for marriage. But, fingers were pointed at Bipasha too; she was linked to her Singularity co-star, Josh Hartnett. However, these are just speculations as the real problem was not spelled out by either Bipasha or John.
