Ryan Reynolds and Scarlett Johansson have reached their first impasse as a married couple. The newlyweds, who were married six months, are rumored to be at war over Ryan’s refusal to quit living high on his hog.

The actor narrowly escaped serious injury when he nearly crashed his beloved motorcycle earlier this month, and his 24-year-old wife thinks the experience should have been enough to convince Ryan to park his bikes–permanently.

An insider squeals to The National Enquirer: “Ryan had to think fast and swerve at the last second to avoid a car making an illegal turn…Ryan thinks he’s invincible because he’s been riding so long and has never had a catastrophic accident…”

The 32-year-old star is a long-time biking enthusiast, who once bragged in an interview: “There are two kinds of riders-those who have gone down, and those who are going to go down. I’ve already gone down a few times.”

The Enquirer spy adds that Scarlett is “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.”

So far, no amount of nagging from ScarJo has been succesfully in getting her hubby to find a less nerve-wrecking hobby. In fact, Ryan is planning a summer riding trip through Alaska on his newest toy, a Paul Smart Ducati bike.

“….Scarlett is angry that he won’t heed her advice. It has ballooned into a major issue.”
