Sofia Vergara and Joe Manganiello, quite possible the most attractive couple in Hollywood, are officially tying the knot! After months of trying to keep the details under wraps, their big day is finally here. The nuptials will take place this coming Sunday, Nov. 22, at a luxurious resort in Florida.

It was instant love for the stunning couple, who got engaged last Christmas after just five months of dating, and they could not be more excited to spend the rest of their lives together.

"When you know, you know, and we knew right away — like, very quickly," the 38-year-old "Magic Mike" actor told Haute Living back in June. "We get along so well together. I'm so lucky to have found that right person for me, and I know she feels the same way."

At first, the couple thought they just wanted to share their special day with some close friends and family, but the more they started planning, the more they realized they wanted to experience this moment with everyone they love. "It's big. We started, like, 'It's only 20.' Yeah, right!" the 43-year-old "Modern Family" actress told "Access Hollywood" during the early stages of their wedding planning. "It's like now there's like pages and pages."

Here are five things you need to know about the superstar couple's upcoming wedding!

1. When & Where
As revealed a few months ago, Vergara and Manganiello are set to wed at the Breakers Palm Beach hotel in Palm Beach, Fla. The event will be a two-day extravaganza that will include a night of cocktails and desserts on Saturday before they say "I do" at 6 p.m. Sunday, according to the lavish white and gold wedding invitations obtained by Hello! magazine. "Love is sweet... let the celebrations begin," reads the invitation. Vergara has always been very upfront about her sweet tooth and love for desserts, so we can only imagine what kind of tasty treats they will be indulging in!

2. The Long List Of Guests
What started off as a small list of 20 guests somehow turned into a list of about 350 to 400 names, according to "Entertainment Tonight." All of Vergara's "Modern Family" co-stars are set to attend and Manganiello, who is a major Pittsburgh Steelers fan, has even invited some of the players.

"It won't really be that top secret, because you can't control 350 people," she told Howard Stern. And she told Ryan Seacrest: "I had to invite, like, all my family.... And Joe has a lot of friends, so it became bigger and bigger and bigger."

There have been more than 100 hotel rooms booked, which run about $600 a night, just for their party alone, as well as about 50 private homes in Palm Beach, according to E! News.

The couple is asking guests to check their cell phones at the door.

3. The Gown
Earlier this month, Vergara was seen walking into Mark Zunino Atelier in Beverly Hills, but it turns out the visit was for one of her reception dresses. As for her actual wedding gown, designer Zuhair Murad has made it, and it's guaranteed to be very similar to her signature red carpet style, which typically includes a gorgeous dress that really shows off her curves and long, wavy hair.

Vergara stunned on the Fall cover of Martha Stewart Wedding and modeled a variety of bridal gowns, giving fans a glimpse of what she could walk down the aisle in. She even revealed that she knows it will take her exactly two hours to get ready because she "has it down to a science," and that she will absolutely be rocking her own fragrance, Sofia, because that's what Manganiello loves. "There's no better reason than that!" she told the magazine.

"We can expect it to really be a curve-hugging dress, because she knows what looks good on her, and that definitely looks good on her," Martha Stewart Weddings editor-in-chief Elizabeth Graves told "Entertainment Tonight." "She definitely loves the look of a red lip, which is modern and exciting to her."

"I think I usually wear what I know looks good on me.... I already know, after so many decades of working, what looks good on me and what works on me so there's no point in changing it," Vergara told E! News. "But, you know, it's a wedding, so it has to be different things, it has to be... maybe a little bit more romantic."

4. Bridesmaids
With so many good friends, amazing co-stars and a large family, you can only imagine how hard it was for Vergara to pick a select few to be bridesmaids, which is why she is sticking to the Colombian wedding tradition of having no bridesmaids. "The one difference that we don't have, for example, [are] bridesmaids," she told Jimmy Kimmel. "We only have flower girls and a ring boy. I don't think that tradition would have ever lasted one second in Latin America. How do you pick your bridesmaids? All your cousins are your best friends — the whole wedding would be dressed in the same outfit!"

Her niece Claudia will have a very special role in the wedding, though. "She's going to be dressed in a beautiful soft dress because she's going to help me holding the flower arrangement," said Vergara. "And she's going to be there fixing my dress."

Vergara's 23-year-old son Manolo will walk her down the aisle.

5. Their First Dance
This is one major moment Vergara left up to her husband-to-be. "He is charged with picking [out] the music," Graves continued to tell "Entertainment Tonight." "First dance is all about him. If it was up to her, she definitely would be dancing to Pitbull."

"I want a wedding where the guests are going to have fun," explained Vergara in Martha Stewart Weddings. "It's about creating memories that you're always going to cherish. That's what's important."
