Will Joe Manganiello And Sofia Vergara Make It Down The Aisle? Joe Is Already 'Flipping Out!'

Watch: Will Joe Manganiello And Sofia Vergara Make It Down The Aisle?

While Sofia Vergara is busy covering the latest issue of Martha Stewart Weddings and talking about her big wedding day, her hunky fiancé Joe Manganiello is freaking out!

“Joe is low-key flipping out right now,” a source tells RadarOnline. This is not good, as they are reportedly getting married in just 3 months!

“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,” the insider continued. So why is Joe suddenly so worried? Part of it could be due to Sofia’s elaborate wedding plans, which seem to be more than Joe anticipated.

“She has made this wedding a huge production with way more guests than he initially wanted,” says the source. Sofia and Joe reportedly have an estimated 300 guests now, with many flying in from out of the country as Sofia is from Colombia.

“I want all the people from Colombia and South America and from Europe to be able to make it to the wedding," she told Entertainment Tonight earlier this year.

And a source tells Radar, “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…It is all just really stressing him out big time.”
