"Magic Mike XXL" could have been the end of Joe Manganiello and Sofia Vergara's relationship.

The hunky 38-year-old actor told reporters on the film's press day on Saturday in West Hollywood that his fiancée threatened to leave him if he insisted on going to the gym after being injured during a stripping scene in "Magic Mike XXL."

"On take one of my finale routine, which we rehearsed and rehearsed and rehearsed and rehearsed, my dance partner did something unrehearsed, and the result was me hearing a loud rip and a pop," he said, according to People. "It was my bicep."

According to Manganiello, the scene involved a "sex swing with monkey bars on top." Despite his injury, Manganiello insisted on filming the remainder of the scene and Vergara was not so happy about his decision.

"Sofia was there that day. We got back to my trailer and, as soon as the door closed, she said, 'If I see you at the gym tomorrow, we're done! I'm going to leave you! That's it!' " the actor recalled.

During Monday's episode of "Kelly and Michael Live," the actor admitted to hosts Kelly Ripa and Michael Strahan that he was nerve-wracked when proposing to his "Modern Family" beauty - especially since some of his proposal speech was said in Spanish.

"I had a big speech in Spanish, and that's what I was nervous about," he shared. "The last thing you want to do is like mess up the Spanish on the proposal to the Colombian woman."
