Dee Devlin is an Irish businesswoman and the longtime partner and manager of former UFC double champion Conor McGregor.
The two have been together since meeting as teenagers at a Dublin nightclub in 2008, long before McGregor became one of the biggest names in combat sports.
Dee has remained his full-time manager and closest confidante throughout his rise to global fame.
She left school at 15 and worked as a waitress and model before eventually joining McGregor’s team full-time as his career took off.
The couple, who have been engaged since 2020, are raising four children together, and McGregor continued referring to Dee as his “wife-to-be” in public appearances.

Dee Devlin Biography
She was born on August 9, 1987, in Walkinstown, a suburb of south Dublin, Ireland. Dee Devlin has two sisters, Sarah and Cathy Devlin, and the three sisters grew up close and have remained connected into adulthood.
Dee was not particularly academically inclined and left school at 15. She took on various jobs, including waitressing and modeling, throughout her late teens and early twenties, well before her relationship with McGregor became the defining aspect of her public profile.
She has generally kept details about her parents and early upbringing private, consistent with her broader approach to keeping much of her personal life out of the spotlight despite her partner’s global fame.
Career
Before Conor McGregor’s fighting career took off, Dee Devlin worked various jobs, including waitressing and modeling, to help support both herself and the couple financially.
At the same time, McGregor trained and pursued his early mixed martial arts career. As McGregor’s profile grew, he entrusted Dee with managing his finances and training schedule, and she has since become an official member of his management and promotional team.
In a 2015 ESPN profile detailing the support system behind McGregor’s rise, Dee described her hands-on role in his fight preparation, explaining that she tries to help him in every way possible, especially during fight camps when cutting weight becomes particularly demanding.
She said her support included cooking, cleaning, and packing his gym bag, providing practical assistance that helped keep his training camps running smoothly.
Dee has also played a direct role in McGregor’s business ventures, particularly Proper No. Twelve, the Irish whiskey brand McGregor co-founded in 2018 with his agent Audie Attar and business partner Ken Austin.
She has regularly promoted the brand on her Instagram account over the years, including celebrating product launches alongside McGregor.
In 2021, McGregor and his partners sold a majority stake in the company to Proximo Spirits, the owner of Jose Cuervo, in a deal worth up to $600 million, making it one of the most lucrative business exits by an active professional athlete.
