Erin McGregor, sister of MMA star Conor McGregor, marked a significant chapter in her life by marrying singer-songwriter Terry Kavanagh in a breathtaking ceremony in Ireland on August 17, 2024.

Surrounded by close family and friends, the couple exchanged vows at the historic Cashel Palace Hotel, symbolizing the culmination of their journey together. Erin and Terry chose Ireland as their venue, with Erin expressing, “Home is where the heart is.”

Having been together for several years, Erin and Terry shared a deeply personal journey leading up to this day. Reflecting on their wedding, Erin said, “We wove the most beautiful and significant parts of our lives into this day, each in its own unique way. To us, getting married means completing our family, the final link in our unbreakable chain.”

The setting of their nuptials, the Cashel Palace Hotel, was the perfect backdrop for their luxurious celebration. Set within a regal manor dating back to 1732, the hotel is located in the heart of Ireland and offers views of the iconic Rock of Cashel.

With a rich history of hosting illustrious guests such as Jacqueline Kennedy, Ronald Reagan, and the late Princess Diana, the meticulously restored hotel provided a glamorous and historic setting for the couple’s big day.

Erin and Terry ensured that every detail of their wedding reflected their love story and the family they have built together, making the day uniquely theirs. The couple shares an 8-year-old son, Harry, and Erin has a 24-year-old daughter, Taylor, from a previous relationship.

On her wedding day, Erin radiated elegance in a custom Zuhair Murad gown, featuring intricate lace detailing and a corset-inspired bodice. She completed her look with Jimmy Choo shoes, which perfectly complemented the regal and glamorous theme of the wedding.

“The gown perfectly complemented the regal and glamorous theme of the wedding, making me feel both sophisticated and radiant,” Erin shared. For the beautiful bride, this moment was a dream come true.

In a 2018 interview with RSVP, Erin expressed her wedding aspirations, “I would love to get married, I would love the big bright dress and the big day out. For me, it has always been a dream of mine to be dressed like a princess. I think that’s what Dancing with the Stars did for me, it made me feel like a princess [sic].”

Terry matched Erin’s elegance, donning a white double-breasted suit paired with black trousers. He completed his look with a black ribbon and a sparkling watch.

The couple’s wedding rings were equally stunning—Erin’s band was encrusted with diamonds, while Terry opted for a simple silver ring.

The couple meticulously planned every aspect of their wedding, incorporating meaningful elements throughout the occasion with the collaboration of Andrea Winckworth from Andrea Winckworth Events.

The couple’s outdoor ceremony was held on the hotel’s sprawling green grounds, featuring a white wedding aisle runner topped with chairs, a floral-decorated arch, and a piano.

One of the most important considerations for Erin and Terry was ensuring the comfort of their son, Harry, who has autism. They chose to hold the ceremony outdoors, allowing Harry the freedom to roam without feeling confined.

“Our absolute must-have for the wedding was ensuring that Harry was as comfortable as possible and able to enjoy the wedding festivities,” Erin said. Their thoughtfulness extended to their guest list, which included 135 friends and family members.

Among the guests was Erin’s brother, Conor McGregor, who attended with his partner, Dee Devlin, and their four children: Croia, Rian, Conor Jr., and Mack. Adhering to the black-and-white dress code, Conor and his family looked striking, with Dee stunning in a chic one-shoulder ensemble.

Conor McGregor’s two children and his partner were not just guests; they were also part of the wedding entourage on Erin and Terry’s big day. Croia, as a flower girl, and Dee, as a bridesmaid, were seen walking down the aisle, while Conor Jr. was positioned at the front of the wedding aisle.

Erin and Conor’s parents, Margaret and Tony McGregor, were also present—Margaret wore a silver gown with a sheer cover-up, while Tony looked sharp in a suit and tie. Terry’s older daughter, Taylor, added to the occasion’s elegance in a sleeveless white dress.

After the ceremony, guests were treated to an elegant cocktail reception featuring a variety of tempting canapés. The drinks menu included cocktails made with Proper Twelve Irish Whiskey and Forged Irish Stout, both owned by Conor McGregor. A six-piece acoustic band provided entertainment as guests mingled and enjoyed the festive atmosphere.

The evening continued with a sumptuous four-course dinner, showcasing the culinary expertise of the Cashel Palace Hotel. The reception tables were adorned with white flowers. Light linens, gold-rimmed glassware, and candles create a warm, sophisticated ambiance, completing the luxurious and meticulously arranged setup.

For dessert, guests indulged in slices of the couple’s five-tier wedding cake, adorned with edible flowers and a large cascading bow. Other dessert offerings included strawberries and vanilla, white chocolate, and matcha tea.

As the night progressed, a 10-piece band played Terry and Erin’s first dance to “Unconditional” by Sinéad Harnett, marking the start of the evening’s celebrations. Surrounded by loved ones, the couple and their guests danced the night away.

Later, Erin swapped her formal wedding gown for a playful white minidress by Folkster, accessorized with bridal-themed sunglasses.

Music continued to fill the air as Casa Disco—a four-member group featuring a DJ, singer, drummer, and saxophonist—took over the stage, keeping the energy high as the celebration carried on late into the night.

The festivities concluded with a spectacular fireworks display that lit up the sky, marking the couple’s union with a dazzling finale. Afterward, everyone enjoyed themselves, with Conor and Dee sharing fun stories back in their hotel room.

Erin and Terry’s love story began in the most unassuming way—at a smoothie bar in Las Vegas. Introduced by a mutual friend with a little encouragement from Erin’s mother, their connection grew quickly.

In a 2018 interview with RSVP, Erin reflected on how their relationship began, sharing, “A friend of mine was partying hard and he introduced us. Neither of us were drinking, I was huge into fitness, and my friend tried to do a Cilla Black by setting us up together.”

Erin shared that her mother immediately vetted her new partner with questions when they first met, as if mentally checking boxes. Erin had given up on love, believing it only existed in fairytales, but after they started texting, she declined his dinner invitation and suggested a walk instead.

“I arrived with no make-up on and wearing leisurewear, which was a big deal for me, and as corny as it sounds, I knew he was the one,” Erin recalled. “You know when you know.”

Despite her initial hesitations about finding love again, Erin found her “happily ever after” with Terry, culminating in their beautiful wedding at Cashel Palace Hotel.
