There may be troubling in paradise for soon-to-wed Sofia Vergara and Joe Manganiello, and it's reportedly all down to the groom-to-be's pre-wedding jitters. "Joe is low-key flipping out right now," a source tells Radar Online. "He said that he does not think he is ready, and all of his friends are telling him to calm down and that he is just having a case of the cold feet."

So what's the main cause of Manganiello's gripe? The scope of the planned event, set for late November in Palm Beach, Florida. "Sofia's having people fly in from all over the world, and two-thirds of the guests that are coming are invited by her. Joe keeps his circle very small," the source says. "She has made this wedding a huge production with way more guests than he initially wanted. It is all just really stressing him out big-time."
