They welcomed their second child to the world last month.
And Conor McGregor looked like he was firmly settling into his new role as a dad-of-two as he enjoyed a family beach day in Miami on Friday.
The Irish UFC champion, 30, was spotted with his newborn baby for the first time as he joined his girlfriend Dee Devlin and son Conor Jr, on a stroll down South Beach's famous Ocean Drive.
Conor looked like he had his hands full as he played with his 18-month-old son Conor Jr, while Dee doted on their newborn baby- rumoured to be a girl name Croia.
The Mixed Martial Arts fighter looked dapper as he showcased his muscular figure in short circular-print swimming trunks, while his adorable tot wore a nappy.
Dee, meanwhile, cut a casual figure in a form-fitting black jumpsuit with white piping. She cinched in her trim waist with a black Gucci belt and wore her brunette tresses in a high bun.
