Scarlett Johansson wants her husband Ryan Reynolds to give up his motorcycle hobby as she fears he would crash. The actress is begging her lover to stop riding the bike after he almost got injured in a recent accident. Now, Scarlett’s fears grew when he told her about a summer road trip across Alaska on his new Paul Smart Ducati bike. A source tells the National Enquirer, “She’s petrified a serious accident is just around the corner. When she asked Ryan to give up motorcycling, he flat out refused. And that led to a pretty heavy argument.”
