Sofía Vergara dishes about her November wedding

Planning a wedding can bring out the monster in even some of the tamest of brides, and Sofía Vergara is admitting that she has fallen victim to bridezilla syndrome.

Appearing on Good Morning America Wednesday, Vergara opened up about her November wedding to Joe Manganiello and revealed some sweet details about her big day and how she and party planner Mindy Weiss are handling everything. But the truth of it, according to the 43-year-old Modern Family star, is that she's leaving everything up to her "great party planner," who apparently has a very tough job considering how much of a bridezilla her client has become.

"I am very detail-oriented so I am kind of like a nightmare," she confessed. "I have a very good memory. If you show me swatches of things, I can in two months exactly remember, 'What happened with the one with the little border that had the little print?' I'm like, really bad."

But for someone who is "really bad" when it comes to her temperament about the wedding, Vergara might surprise you with this little fun fact: She doesn't have her wedding dress yet!

"I know who's making my dress, but it's not ready," she explained. "They're making it far away so we'll see what happens when it arrives and I'm very excited. But we're almost ready."

The couple, who got engaged on Christmas Eve last year as E! News exclusively reported, have been turning to each other during this exciting time. Thankfully, Manganiello is more than patient and willing to help with all the planning, which really means he sits back and let Vergara do whatever she wants.

"He's a pleasure to be doing this with. He lets me do whatever I want," Vergara quipped. "I show him options that of course I already want and I'm happy with, so whatever he's going to pick I already like."

With both stars' schedules being so hectic, however, they almost decided to pull an audible and elope. But her family wouldn't stand for that. "We thought, 'Let's not deal with this craziness,' because we're super busy and to plan a weekend that we can both be there and have a little honeymoon or something," she said.

"But my family was very difficult. My family started having seizures and heart attacks, complaints and emails with bad words. They wanted a party. They needed a party," she continued. "The last party I did was when I was turning 40 so it's been like three years so they wanted something."
