All About Conor McGregor’s Fiancée, Dee Devlin

Conor McGregor has been in a relationship with Dee Devlin for over a decade.

McGregor and Devlin first met in 2008. Though they grew up in nearby towns and had a handful of mutual friends, they didn’t officially meet until they were both at the same nightclub in Dublin, where Devlin was working at the time. They hit it off and messaged online before making things official.

The couple share four children: son Conor Jr., born in May 2017; daughter Croai, born in January 2019; son Rian, who arrived in May 2021; and son Mack, born in November 2023.

After more than 10 years together, the former UFC champion proposed to Devlin on Aug. 9, 2020, his future bride’s 33rd birthday.

However, their relationship made headlines in July 2025, when the MMA fighter was spotted kissing a mystery woman in Fort Lauderdale, Fla., per photos obtained by The Sun. McGregor has yet to speak publicly about the pictures.

So who is Conor McGregor’s fiancé? Here’s everything to know about Dee Devlin and her relationship with the MMA fighter.

She officially met McGregor at a nightclub

Devlin grew up in Walkinstown, which is near McGregor’s hometown of Crumlin. Although they ran in similar circles, they didn’t officially cross paths until a night out in Dublin. At the time, McGregor had recently quit his plumbing apprenticeship and decided to pursue his MMA career.

“I knew her a bit beforehand, but I think the first time I spoke to her properly was when I saw her in a nightclub,” McGregor told VIP Magazine in July 2015. “I asked her to come over and we just started chatting. She seemed like a nice girl, and I like good girls.”

As for Devlin, the attraction was instant. “He’s very funny,” she told the outlet. “He always keeps me entertained and makes me laugh. He was already training when I met him, so I really admired his dedication to that, too.”

However, she did have one hesitation when it came to his new career choice. “When I first met him, though, he didn’t have cauliflower ears, and I remember thinking: ‘Oh God, what if he gets cauliflower ears, that would be terrible!’ He has them now and I don’t remember him without them,” she admitted.

She and McGregor share four kids

The couple welcomed their first child, Conor Jack Jr., on May 8, 2017, at Coombe Maternity Hospital in Dublin.

“The birth of my son could not have came at a better time for me. I had won the second world title, I was a two-weight world champion. Exactly what I did, is what I set out to do,” McGregor said.

McGregor later recalled the “perfect” moment when he discovered that he would be a father. They were at their beach house in California, and after taking a pregnancy test, Devlin came up to him and told him the news.

Understandably, the athlete still had some worries about becoming a first-time dad, especially with his high-profile career. “I’m crapping me jocks, I’m not going to lie. I don’t even know what way to take it,” he said in a post-fight press conference. “I don’t even want to do the celebrity type s—. I hate all that. I don’t want my family to be like that.”

However, McGregor’s fears quickly subsided after Conor was born.

“I’m very proud and very blessed everyday because the birth of my son has made me softer where I need to soften up,” he said during an appearance on RTE’s The Late Late Show. “I’m overcome with joy and love. I never thought I would be that way.”

In January 2019, the couple welcomed their second child, daughter Croia, whose name has an Irish origin and means “of the heart.” Devlin went on to give birth to two more sons — Rian in May 2021 and Mack in November 2023.

The entire family, minus baby Mack, attended the London premiere of Road House, an action-packed film starring McGregor and Jake Gyllenhaal, in March 2024.

She works on her fiancé’s team

Devlin has held many different jobs over the years, working as both a waitress and model when she was younger. Once McGregor’s career started taking off, however, she changed professions and became a member of the fighter’s team.

In a 2015 ESPN profile about the supporting cast surrounding McGregor, Devlin outlined all of the ways she helps her significant other prep for a big fight.

“I definitely try to help him out all the time, even without realizing it. Especially around a fight because it’s such a tough time with his weight,” she said. “I cook, clean, pack his gym bag, all that kind of stuff.”

She also works on McGregor’s management and promotional teams, and assists with his whiskey brand, Proper No. Twelve.

She and McGregor got engaged in 2020

In August 2020, McGregor proposed to Devlin on the week of her 33rd birthday. He shared the news via Instagram with a selfie of the couple, proudly showing off her new square engagement ring.

“What a birthday, my future wife,” McGregor captioned the snap. Numerous colleagues of McGregor shared their congratulations in the comments section.

“Congratulations to you and Dee!!!” Artem Lobov responded. Holly Holmad added, “Congratulations! Many blessings ❤️.”

Devlin also celebrated the pair’s engagement on her own Instagram sharing a photo of the two smiling on a boat. “Forever love, my fiancé ❤️✨,” she wrote.

During a January 2021 interview with Extra, McGregor shared details about what his ideal wedding day would look like.

“My wedding is going to be extravagant, that’s for damn sure,” he said. “We are gonna have the best of the best of the best, and then more to the best. We have got to find the location; it’s going to be Ireland, I’m gonna get married in the Emerald Isle, and then figure it out, so it’s a big process. Let’s see what happens, I’m ready for it all.”

She supported McGregor during his 2024 sexual assault case

A woman named Nikita Hand sued McGregor in 2021, accusing him of “brutally” raping and battering her while she was intoxicated in December 2018, per The New York Times.

In November 2024, McGregor was found liable in the civil rape and sexual assault case and was ordered to pay damages totaling nearly €250,000.

Devlin was seen supporting her fiancé at the courthouse.

In now-deleted posts on X, McGregor claimed the incident was “consensual,” said he planned to appeal the decision and apologized to Devlin.

“I know I made mistakes. Six years ago, I should have never responded to her outreaches. I should have shut the party down,” he wrote. “I should never have stepped out on the woman I love the most in the world. That’s all on me.”

McGregor is currently appealing the ruling, per the BBC.

McGregor was seen kissing another woman in July 2025

In July 2025, McGregor was seen kissing a woman who was not Devlin while on a beach in Florida.

The mom of four has not addressed the photos obtained by The Sun, and neither has the MMA fighter.
