After announcing the birth on Monday (15 June), former TOWIE star Billi has only referred to her new arrival as "Little AC", leading to speculation he'd been named after his dad, Andy Carroll.
Today (17 June), Billi revealed what the couple have chosen to call their son in a touching Instagram post, which showed the newborn lying by a stunning floral display, which spells out his first name.
"Arlo Thomas Carroll #LittleAC @andytcarroll", proud mum Billi wrote alongside the sweet snapshot.
After leaving the hospital yesterday, it seems Arlo is settling in very comfortably to his new home, with a nice snooze on the plush carpet.
Proud parents Billi and Andy both shared their happiness on Twitter, with Billi saying: "Welcome To The World Our Beautiful Baby Boy."
Footballer Andy also gushed: "Welcome to the world Little AC!! 9 Months of cooking and what a wonderful job you have done…"
