The nuptials mark Vergara's second wedding -- she wed her high school sweetheart, Joe, when she was 18, but they split three years later -- and Manganiello's first.

The couple have been dating since July 2014, after she ended her engagement to businessman Nick Loeb in May. After a whirlwind romance, Manganiello popped the question on Christmas Day.

In June, Vergara explained to ET why she decided on a destination wedding. "I want all the people from Colombia and South America and from Europe to be able to make it to the wedding and Los Angeles is very far away from everything," she said. She also confirmed that she's not having any bridesmaids or having a bachelorette party, citing her Latin America roots.

"In Latin America we don't do bachelorette parties," she explained.

Vergara has also admitted that she initially though Manganiello was too good-looking to date!

"I didn't want to go out with him for a long time because I thought he was too good-looking," she confessed to InStyle in September. "Like, it's too much work, and I'm older. I'm 43 years old. I don't want to deal with a guy that every girl is after, you know? But then I gave him a chance. I realized he's not like a typical handsome guy. He's not vain. He's very serious, very straightforward, very easy."

For his part, Manganiello has admitted to his immediate attraction to the Modern Family star, when the two first met at the White House Correspondents' Dinner in May 2014. The Magic Mike actor was even caught checking out her famous derriere, though the two had yet to start dating at the time.

But will the two be expecting kids soon? According to Vergara, it's a real possibility.

"He's younger than me and he's never had kids, so of course if we can do it, why not?" Vergara told ET in January at the SAG Awards. "It needs a lot of planning, but we have to leave it to God to see if it happens."
