Conor McGregor and his longtime partner Dee Devlin were finally married in a lavishly symbolic ceremony at the Vatican on 12 December 2025. The event perfectly encapsulated the UFC star’s flair for the dramatic, marrying historic solemnity with opulent celebration. While securing the ceremony at the historic Chiesa di Santo Stefano degli Abissini cost a surprisingly modest fee, the total expenditure for the multi-day wedding is estimated to have reached a staggering €150,000 to €250,000.
The wedding, which McGregor had promised would be “extravagant” back in 2021, served as both a deeply personal milestone for the couple, who have been together for nearly two decades and share three children, and a quintessential public display of “McGregor” grandeur.
The Vatican Ceremony: Historic Setting, Modest Price Tag
For the couple, the choice of the Vatican City was rich with personal and symbolic meaning. The ceremony took place at the Chiesa di Santo Stefano degli Abissini, a small, ancient church nestled behind St. Peter’s Basilica known for its stunning Byzantine mosaics and historic significance.
Contrary to expectations of immense cost, the price to secure a ceremony in this exclusive location was reportedly just €1,200. This fee covered the use of the church and the services of the officiant. The low cost, however, belied the immense privilege and significant behind-the-scenes effort required to host a high-profile figure like McGregor within the Vatican’s walls, which included elevated security planning.
The Lavish Reception: Where the Budget Soared
If the ceremony was defined by understated history, the reception was pure McGregor spectacle. The celebration was held at a luxury castle venue in the Roman countryside, transformed for the evening into a scene of opulence.
Key elements that drove the cost into the six-figure range included:
- Extravagant Décor: The venue was adorned with thousands of white roses and bespoke floral installations.
- Live Entertainment: A full string quartet and choir performed during the ceremony, followed by a live band and dancers for the reception.
- Premium Amenities: A dedicated cigar bar featuring high-end cigars and a premium open bar served guests throughout the night.
- Grand Finale: The evening culminated in a private fireworks display, ensuring a memorable finale.
These details, coupled with luxury accommodations, gourmet catering, and security, are what pushed the total cost toward the estimated quarter-of-a-million-euro mark.
A Union Nearly Two Decades in the Making
The wedding celebrated a partnership that has been the foundation of McGregor’s life and career. McGregor and Devlin met in Ireland before his rise to global fame, and she has been a constant presence, managing their business affairs and raising their three children: Conor Jr., Croía, and Rían.
In his speech, McGregor credited Devlin as his “rock,” highlighting her unwavering support through his meteoric success in the UFC, his foray into boxing, and his various business ventures. The wedding served as a very public acknowledgement of her central role in the “McGregor” empire.
