As Conor McGregor prepares to battle Floyd Mayweather in August, fans are wondering about the UFC fighter's personal life and his longtime girlfriend has been sharing tons of special photos online.

Although McGregor isn't married, he and Dee Devlin have been together for nearly a decade and they welcomed their first child together earlier this year.

"Dee and Junior are doing great everyone! Thank you for all the kind words, I am one proud and blessed Daddy," McGregor wrote to his fans and followers on Instagram in May, along with the first photo of his longtime girlfriend and their baby boy.

After welcoming their child over a month ago, McGregor has made it clear that he is one proud papa by sharing a bevy of photos of his son on his Instagram page.

Most recently, the fighter posted a photo of himself holding his baby with a caption that read, "My little man is going on his first holiday without me today."

McGregor also posted a photo of his son behind the wheel of a mini Lamborghini.

McGregor and Devlin met in a nightclub eight years ago and have been together ever since.

"My girlfriend worked very hard throughout the years and stuck by me when I had essentially nothing," McGregor recently gushed to the Irish Mirror. "For me to be able to take her out of work, give her everything she's ever wanted and to travel the world with, fills me with pride."

As for Devlin, she recently said that she fell for McGregor right away.

"He's very funny - he always keeps me entertained and makes me laugh," she told VIP Magazine. "He was already training when I met him, so I really admired his dedication to that, too."
