The couple tied the knot at L'Olivetta, a villa owned by Dolce & Gabbana in Portofino, Italy, on Sunday surrounded by their closest friends and family.
During the reception — which was hosted at a nearby 16th-century castle, Castello Brown — Kourtney, 43, and Travis, 46, shared a sweet dance with one another to Elvis Presley's "Can't Help Falling in Love," which was performed by Andrea Bocelli.
Kim Kardashian shared a video from the romantic moment on her Instagram Story. In the clip, Kourtney, dressed in a custom white corseted mini-dress with a matching shot veil, and Travis, outfitted in a sleek black suit — both by Dolce & Gabbana — danced behind Andrea, 63, and his son Matteo, who played piano.
As the Italian musician sang the infamous tune, Kourtney wrapped her arms around her new husband, the two swaying back and forth to the sound of backing instruments.

"Domenico Dolce called us last week and asked if we could create a unique surprise for his friends Kourtney and Travis, and all the Kardashian family," Andrea and Matteo, 24, previously told PEOPLE in a joint statement. "Portofino is in everyone's heart and we replied positively to such a lovely moment in their life. We wish them all the best for their future together."
Added an insider of the performance between the father and son: "It was an incredible moment and a very special performance."

Travis proposed to Kourtney in October 2021 on the beach in Montecito, California.
The romantic moment saw the couple standing in a heart made of roses and candles. The proposal and a celebratory dinner with family afterward were featured on Hulu series The Kardashians.
Their Italian wedding is the third time Kourtney and Travis have tied the knot. The first time the couple sparked marriage rumors was on April 4 when they had a "practice wedding" at a Las Vegas wedding chapel. The spontaneous exchange of vows included an Elvis impersonator as the officiant and took place in the middle of the night. "Can't Help Falling in Love" was also said to play there, too.
On May 15, the pair were legally wed at a California courthouse. A source told PEOPLE the wedding took place in preparation for their Italy nuptials — to make sure the wedding would be legal.
