Ed Westwick and Amy Jackson tied the knot.
After getting married during a small civil ceremony at The Connaught Hotel in London on August 9, the Gossip Girl alum, 37, and the Supergirl actress, 32, said "I do" for a second time on Saturday, August 24, during a destination wedding in Italy.
The glamorous couple invited 220 guests, who traveled from the U.S., India, and various parts of Europe, to join them for a three-day-long celebration on the Amalfi Coast.
Jackson told PEOPLE magazine the picturesque region was "the perfect place" to host their nuptials, citing its "timeless romance and vintage charm."
"We wanted a wedding spot that was not only naturally beautiful, surrounded by the ocean, hills, and vineyards, but also unique, and we found just that," the Supergirl star added.
Guests included Westwick's Gossip Girl costar Kelly Rutherford, model and actress Daisy Lowe, comedian and actor Jack Whitehall and his partner Roxy Horner, film producer Mohammed Al Turki, and cosmetics mogul Dr. Barbara Sturm.
The festivities kicked off on Friday, August 23, with a sunset cruise on the Motonave Patrizia. "We sailed along the coastline of Ravello, Positano, and Sorrento and then anchored at Capri for a dip [in the sea] as the sun set behind the Faraglioni rocks," Jackson said.
On Saturday, the couple held their ceremony at the historic Castello Di Rocca Cilento, nestled in the hills and offering sweeping views of the sea.
"It was the perfect setting, offering old-world charm and the ideal backdrop for the classic styles of our Italian designers Giorgio Armani and Alberta Ferretti," Jackson said.
To infuse a sense of home into their special day, they filled the 16th-century venue with flower arrangements and other flora.
"We recently moved into our new home in the British countryside, and our garden brings us so much happiness and peace. We wanted to recreate that enchanted garden feel for our ceremony," Jackson noted."Walking down the aisle felt like stepping into an enchanted world,".
Jackson's 4-year-old son, Andreas — whom she shares with ex Andreas Panayiotou — served as Westwick's best man, alongside the actor's friend Mike.
The trio made their walk to the James Brown hit "I Got You (I Feel Good)," performed by a string quartet.
"We both wanted [Andreas] to be an integral part of this special moment," Westwick — who donned an Armani tuxedo with a white jacket and black pants — told the outlet. "He walked down the aisle with me, carried the rings, and waited for his mother with me."
The bride added, "I think it’s a really beautiful way to honor their bond and make sure he feels part of our celebration."
Jackson — who made her way down the aisle accompanied by flower girls to her favorite song, "Nuvole Bianche" by Ludovico Einaudi — donned a custom-made gown by Italian designer Alberta Ferretti, with whom she has collaborated for years. The gown was made from a light and airy mikado fabric, ideal for the Italian summer heat.
"The dress Alberta created made me feel like the best version of myself, indulging my hopeless romantic side for the day," she noted, before sharing a favorite detail of her bridal look. "The 15-foot hand-embroidered veil brought me to tears when I first saw it."
For the reception, Jackson wore a second look by Pronovias Atelier, inspired by her love for the French couturier Madame Grès' draped, sculptural designs. "By combining a modern embellished corset and diamond rain-like gloves with vintage elements, [it's] the perfect fusion of past and present," Jackson said of the dress.
Since she and Westwick did traditional vows at their London ceremony, they took this occasion to recite handwritten vows to each other.
"It felt like the perfect way to share our love story," Jackson explained. "Using our own words allowed us to make personal promises for our future, and also look back on our journey together so far."
"Even among the 220 guests, it felt like it was just us two in the room," she added.
After sealing things with a kiss, the newlyweds exited the ceremony to Stevie Wonder's "Signed, Sealed, Delivered," with their loved ones dancing down the aisle behind them.
After dinner, the bride and groom took to the dance floor for their first dance to the Frank Sinatra classic "Fly Me to the Moon".
"The bridesmaids were briefed to crash our first dance after 60 seconds. We managed to get our moves in during that time — anything longer would have been entertaining for all the wrong reasons!" Jackson recounted.
Westwick's friend and For You band member Hans Kristian Nordin then remixed the Sinatra song and segued the music to "Dancing in the Moonlight" for everyone to join in and dance along.
The wedding weekend capped off on Sunday, August 25, with a farewell brunch at the Giardini del Fuenti beach club in the town of Vietri sul Mare.
The event was all about "kicking back and relaxing," Jackson said, sharing that the group enjoyed a family-style Italian meal "under the lemon trees followed by an afternoon of sunbathing and taking in the beautiful view."
Jackson noted the event was "the perfect farewell" to their loved ones following an unforgettable weekend spent celebrating together. "We laughed and ate all afternoon until the sunset," she reminisced.
The couple — who first met in 2021 and got engaged in Gstaad, Switzerland, in January 2024 — tell PEOPLE they are looking forward to married life and experiencing even more adventures together.
"For me, [marrying Westwick] means having a life partner to adventure with, to share love and support, to create a beautiful family and to have each other's backs throughout all of life's moments," Jackson said. "It's about building a future together and creating endless memories, knowing that we are a team through it all."
"This all represents a new level of energy for a new adventure — the best one you can possibly have," Westwick added of his new wife: "I spent my life wondering who she would be, and then I found her."
The pair also hopes to grow "their little family" sometime in the future. "I adore how Ed is with my son Andreas, and I can't wait to see him as a father one day too."
The two had planned to whisk away on a honeymoon to Kenya, but they had to put an end to the plan as Westwick begins filming his new show, Sandokan, immediately after the wedding.
"When we do go, the trip will be so amazing," the actor said. "We adore nature and wildlife, and to witness this incredible location we haven’t been to before will be sensational. A real bucket list trip for us."
Jackson promised, "I won’t be letting the honeymoon slide. Having Ed to myself for a week is my first request as Mrs, Westwick."
