How many children does Conor McGregor have and how old are they? Inside the UFC fighter's family life with partner Dee Devlin - including stunning £2.5m house and huge net worth

Conor McGregor recently celebrated the birth of his son Mack with his partner Dee Devlin, adding to their expanding family. 

The Irish UFC superstar juggles life as a family man with his business interests and training, with his long-awaited return to the octagon expected in 2024. 

McGregor still lives and works in his homeland where he can be close to his family and SBC Gym, where he honed his craft in the early years. 

Here, we take a look inside McGregor's support system, where he lives and his incredible net worth.  

How many children does McGregor have?

Mack, born four days ago, is the fourth child in the family. McGregor and his partner Devlin have a quartet under 10 years old. 

Their firstborn was Conor Jr, who is now six and is regularly seen on his father's Instagram page learning the basics of the fight game. 

McGregor's only daughter, Croia, is four and his second son Rian, two, was the youngest until Mack's arrival. 

Is he married?  

McGregor is not married to long-term partner Dee Devlin, although they are engaged after he proposed in August 2020 while they were celebrating his 32nd birthday in the south of France. 

They met as teenagers in a nightclub and Devlin is a key part of the MMA star's story having supported him when he was unemployed and committing himself fully to making it as a professional fighter. 

He previously told VIP magazine: 'I asked her to come over and we just started chatting. She seemed like a nice girl, and I like good girls.'

Devlin added: 'He was already training when I met him, so I really admired his dedication to that.'

McGregor also told MMA Fighting: 'I love to spoil her. She does not work anymore, I hired her to the business. She works for me now and collects the cheques.

'Dee worked very hard throughout the years and stuck by me when I had essentially absolutely nothing. I only had a dream that I was telling her.

'For me to be able to take her out of work, give her everything she's ever wanted and to travel the world with her fills me with pride. It keeps me going. We've been together a long time. She's been through it all with me.'

Where does he live? 

McGregor lives in Kildare, about a 40 minute drive from Dublin. He purchased the property in 2019 after becoming two-weight champion when he was at the peak of his powers in the octagon. 

The house was bought for around £2.5million and it previously belonged to the son of former taoiseach (prime minister) Albert Reynolds's son, Albert Jr. 

It is known as The Paddocks, comprises of five bedrooms and six bathrooms, a living room, dining room, kitchen and games room and stables near the landscaped garden looking out onto the river Liffey. 

McGregor and Devlin were understood to be interested in a couple of other properties in the same area. 

One of them was owned by Formula One legend Eddie Irvine and U2 lead singer Bono would have been their neighbour had they opted for that one.  

What is McGregor's net worth?

McGregor claimed his net worth to be in the region of £536million earlier this year in an interview with Megan Olivi.

His fortune from fighting has been enhanced by his businesses. McGregor sold his stake in Proper No. 12 Whiskey for an estimated £128m and interest in the Forged Irish Stout he launched is spreading like wildfire. 

A top US sports analyst claimed that McGregor will become a billionaire by this year. 

He's not there yet, but with the 35-year-old father-of-three's collection of cars, yachts and watches, has plenty to keep himself entertained. 

What does he spend his money on?    

The former UFC lightweight double-champion owns two Lamborghinis and four Rolls Royce's in a supercar collection worth over £2.5m. 

McGregor’s custom Rolls-Royce Ghost, which is worth a cool £280,000, features an image of himself with his trademark moniker ‘Notorious’ on the side of the car.

The stunning matte black motor was given to him as a gift by Rolls Royce ahead of his New York showdown with Eddie Alvarez in 2016 at UFC 205.

He is also said to own a Rolls-Royce Wraith which is worth roughly £250,000, a Rolls-Royce Dawn (£285,000) and Rolls-Royce Phantom VIII (£340,000).

McGregor has two Lamborghini Aventadors, one of which is in white and costs £280,000 while the other is a green convertible worth £276,515.

Other cars in the Irishman’s fleet include a £200,000 BMW i8, a £198,000 McLaren 650S sports car and a £110,570 Mercedes-AMG S 550 Coupe.

On top of this he also has a £110,000 Bentley Continental GT, a £75,000 Cadillac Escalade and two Range Rovers worth over £90,000 each.

McGregor has amassed the ultimate watch collection too, ranging from loud multi-million pound pieces by Jacob & Co. to more traditional Rolexes and Patek Philippe's.

And his riches extends from the land to the sea. In 2019, McGregor bought a Prestige 750 yacht which has a price tag of around £3m.

The 75-foot boat was inspired by Muhammad Ali and features a quote from him that reads: ‘He who is not courageous enough to take risks will accomplish nothing in life.'

Two years later he also purchased a £2.6m Lamborghini Tecnomar 63 motor yacht, one of only 63 in the world.
