The Wedding of the Decade: Dee Devlin and Conor McGregor Tie the Knot

The long-awaited wedding of Conor McGregor and Dee Devlin finally took place in a stunning, private ceremony in Vatican City in December 2025. The event, five years after their engagement in 2020, was a lavish affair befitting the couple's billionaire status, drawing attention from international media and fans across the globe. The choice of the Vatican for the ceremony underscored the couple's Irish Catholic roots and provided a dramatic, historic backdrop for their vows.

The wedding marked the culmination of a 17-year relationship that began in a Dublin nightclub, where Devlin supported McGregor when he was an aspiring, struggling fighter living on welfare. Her role as his emotional and financial rock during his formative years is a key part of his personal narrative. Devlin is not just a partner but also a crucial member of "Team McGregor," acting as his financial manager and business advisor, handling his schedule and ensuring his personal life runs smoothly amidst the chaos of his professional commitments.

A Partnership Beyond Romance

Dee Devlin’s influence extends far beyond her role as a wife and mother. She is instrumental in managing the vast McGregor empire, which includes his Proper No. Twelve Irish Whiskey brand, his clothing line, and various other investments. This powerful partnership is a testament to their enduring bond and shared vision for their future. The couple’s ability to navigate the intense public scrutiny and the demands of a global superstar's career while raising four young children is a remarkable feat.

The marriage and the growing family are seen by many as a grounding force for the often-controversial fighter. As McGregor pivots between high-stakes fights and major business deals, his family remains his constant priority. He frequently speaks about the pride he takes in his children, Conor Jr., Croía, Rían, and Mack, and the importance of providing them with a life he never had growing up in Crumlin, Dublin. This focus on family is a central theme in his life as he enters the next chapter of his career and personal life.

The Extended McGregor Clan: Parents and Siblings

Topical authority on the McGregor family is incomplete without mentioning the wider clan, who have also played a significant role in his life and public image.

Tony and Margaret McGregor (Parents)

Conor's parents, Tony and Margaret McGregor, have been supportive figures throughout his career. Tony, a former taxi driver, and Margaret, a homemaker, raised Conor in the working-class suburb of Crumlin. Their move to a more affluent area, Lucan, in 2005, was a significant moment in the family's history, though McGregor has often reflected on his humble beginnings.

Erin and Aoife McGregor (Sisters)

Conor has two older sisters, Erin and Aoife. Erin McGregor is a well-known personality in Ireland, having appeared on the Irish version of Dancing with the Stars. She is also a fitness enthusiast and bodybuilder. Aoife McGregor is also a key figure in the family, often appearing at her brother's fights and public events, showing the close-knit nature of the entire McGregor clan.

The entire family—including his parents, sisters, and now his wife and four children—represents a powerful support system, often traveling with him and celebrating his victories. Their collective presence underscores the importance of his Irish roots and family loyalty in his life, providing a stable foundation for "The Notorious" as he continues his legendary career.
