Celebrity couple Scarlett Johansson and Ryan Reynolds, who married last September, reportedly got into so big a spat that Reynolds decided to sit out a promotional trip to San Diego.

“They got in a huge fight just before they were going to Comic-Con,” a source said, according to Fox News. “Ryan refused to attend the conference and he told Scarlett she could go alone. She got so angry she threatened to take off her wedding band.”

Johansson turned up at the convention to promote Iron Man 2, but Reynolds — who was recently cast in the upcoming Green Lantern — stayed home, which “angered the executives” behind the superhero film.
