After tying the knot, the couple treated their guests to a late-night dance party, where A-list pals Channing Tatum and Jenna Dewan-Tatum hit the floor with the newlyweds. And when the deejay played "I Want It That Way" by the Backstreet Boys, Manganiello recreated his thrusting convenience store routine from Magic Mike XXL.
Vergara, 43, and Manganiello, 38, wed Sunday at The Breakers Resort in Palm Beach, Florida. A "charming" little boy dressed in all white served as their ring-bearer- along with three flower girls in sparkling white dresses, a source tells PEOPLE. The romantic ceremony eschewed tradition for more personal touches: The Modern Family star walked down the aisle (on the arm of her 23-year-old son Manolo Gonzalez-Ripoll Vergara) to an instrumental version of Amanda McBroom's "The Rose", and the bride and groom said "I will" instead of exchanging "I dos."
"Joe made a beautiful speech pledging his eternal love and adoration in both English and Spanish, followed by Sofia's which she preambled by the statement, 'Oh, mine is not so good!' " the source says.
At the opulent dinner afterward, red roses and orchids cascaded down from the ceiling alongside crystal chandeliers. Guests enjoyed caviar, crab and lamb while seated at tables covered with centerpieces of crystal candlesticks and red flowers. A live band called JB Project from West Coast Music played, and Manganiello serenaded Vergara (again!) with Guns N Roses' "Sweet Child O' Mine." But the couple had one more musical surprise in store: Pitbull took the stage for a set.
The stars shared their first dance to "The Way You Look Tonight" by Frank Sinatra.
"There were lots of very sweet moments," the source says of the reception. "Joe made a touching speech about his love for his wife and how he fell in love with her so entirely and was so bowled over by her the first time he met her!"
Manganiello proposed to Vergara last Christmas during a trip to Hawaii. They began dating in July 2014 after the actress caught the True Blood star's eye during the White House Correspondents' Dinner.
"She's got the curves, she's got a beautiful face, beautiful hair, just gorgeous," Manganiello said after being named PEOPLE's Hottest Bachelor. "Naturally beautiful. She's feisty!"
