We all know how the otherwise strong and beautiful Bipasha Basu is scared of water as she does not know how to swim. While shooting for her upcoming horror love story Alone, there was a scene that required her to jetski on the backwaters of Kerala, sitting behind her costar Karan Singh Grover. Bipasha was really scared as it is, doing this scene, but she reluctantly agreed given the requirement. At a point while shooting, Karan had to make a sharp turn and as he did that, the jet-ski overturned. Bipasha not only fell off into the water, but obviously as she did not know how to swim, she started sinking. The crew was far off with the camera, but Karan immediately jumped to her rescue and like a macho man and hero, saved his actress from drowning. A shocked Bipasha was brought on another boat and she took a couple of hours to get back to normal. But given the professional she is, she went back to completing the shoot that day. Well done, Karan. We do hope Bipasha will take swimming lessons now.
