Who Is Dee Devlin? All About Conor McGregor's Fiancee Amid Marriage Rumors

17 hours ago 1

Conor McGregor sparked a fresh wave of speculation after sporting a new ring that appeared to be a wedding band and hinting at marriage plans with his longtime partner, Dee Devlin.

The UFC star addressed his personal evolution and relationship, describing Devlin as his “wife-to-be” during a speaking engagement in Rome on October 23, 2025, ahead of a Bare Knuckle Fighting Championship event.

“I am not here just by chance. There is a higher power, God, that dictates my journey and all of our journeys,” he said. “I live my life by God’s word, since around the last time you mentioned at the last event, I have engaged on a spiritual journey. I am saved. I am healed.”

“On the back of that, the world is in for a treat,” the Irish mixed martial artist announced. “My competitive spark that was once in my heart is now a roaring blaze. I’m eager.”

“Right now I have to dial myself in and go inward, and that I’ve done, and now I’m in a stage where I come back and show what I’m about,” McGregor continued. “Now I’m here with my own family, my beautiful children, my fiancée, wife-to-be soon.”

“People want to hear from me, I needed time,” McGregor wrote via X in a now-deleted tweet. “I know I made mistakes. Six years ago, I should have never responded to her outreaches. I should have shut the party down. I should never have stepped out on the woman I love the most in the world. That’s all on me.”

He continued, “As much as I regret it, everything that happened that night was consensual and all the witnesses present swore to that under oath. I have instructed my legal team to appeal the decision,” he said. “I can’t go back and I will move forward. I am beyond grateful to my family, friends and supporters all over the world who have stayed by my side. That’s it. No more. Getting back to the gym — the fight game awaits!”

McGregor lost his appeal against the verdict in July 2025.
