Ed Westwick married his longtime love Amy Jackson in a stunning ceremony at the Castello di Rocca Cilento—a five-star hotel located inside of a walled-off castle in Rocca Cilento, Italy, near the Amalfi Coast.

The Gossip Girl alum looked dapper in a white Giorgio Armani tuxedo jacket, black pants, and a black bowtie, sharing gorgeous photos to Instagram on Aug. 25 and writing, “The journey has just begun.”

The bride was breathtaking in a strapless white Alberta Ferretti gown with a multi-tiered lace veil.

Prior to their glam ceremony, the couple invited their guests onto a yacht for an epic welcome party, sailing around Capri and the Amalfi Coast.

“Let the fun begin!” Amy captioned a clip of the festivities on Aug. 26. “We set sail along the Amalfi Coast with all our friends and family aboard. It was the perfect start to our Love Story Weekend as the sun set behind the Faraglioni Rocks.”

The pair got engaged in the Swiss Alps back in January after more than two years together.

The Supergirl actress, 32, is mom to 4-year-old son Andreas with her ex George Panayiotou and regularly shares photos and videos of her little guy with Ed.

But the 37-year-old isn’t the only Gossip Girl star to embark on a new chapter. In fact, his ex and former costar no comma Jessica Szohr got married earlier this month to hockey star Brad Richardson in a boho-chic ceremony in Flagstaff, Ariz.

For Jessica’s ceremony, fellow costar Chace Crawford attended the nuptials along with maid of honor Nina Dobrev and her boyfriend Shaun White.

Though Ed and Jessica ended their on-and-off romance in 2010, he went on to find his match in Amy. The couple live outside of London in a country house they recently renovated with Amy sharing a video in January on Instagram, writing, “Our dream home is now a reality.”
