Conor McGregor and Dee Devlin reportedly welcomed a baby girl to their family.
The newborn is the couple's second child, after their son, Conor Jnr., was born in May 2017.
The Irish Daily Star report that the pair welcomed a baby girl, with the proud parents choosing a very unique Irish name for their little one.
The publication report that Dee and Conor chose the name Croia, which is thought to mean "of the heart" or "little heart".
The UFC fighter confirmed the news of their little one's arrival on social media on Friday, as he praised his "SuperMam" partner, Dee.
He shared a photo of himself carrying the newborn out of the hospital, with Conor Jnr. walking beside him.
He captioned the photo:
"Heading home with my two healthy babies and an energized and healthy SuperMam.
"2019 is off to the best start!
"Thank you for the well wishes everybody!"
Fans rushed to congratulate Conor and Dee about their new arrival.
One person said:
"Another McGregor - just what the world needs. Congrats !!"
Another person added:
"Congratulations to you and your family, man."
Dee announced that they were expecting their second child in July 2017, as they celebrated Conor's birthday.
She captioned the photo:
"Love you to bits from me, Conor Jr and the bump."
