Billi Mucklow welcomed her first child into the world with footballer fiancé Andy Carroll on Monday, but has only just revealed the name of her baby son.
Posting a picture of the teeny tot on Instagram, TOWIE star Billi spelled out his name in flowers.

“Arlo Thomas Carroll #LittleAC @andytcarroll,” she captioned the adorbs photo.
According to our extensive research (i.e literally just typing four letters into Google and hitting enter), the meaning of Arlo is ‘army hill’, which is nice.
It also means ‘fortified hill’ and derives from the Anglo-Saxon ‘here’, so hopefully little Arlo’s got an excellent career as a hiking expert-slash-battle re-enactor lined up.
Earlier this week, Billi announced Arlo’s arrival with a picture of the boy snuggling up to his parents.
“Welcome To The World Our Beautiful Baby Boy □ @andytcarroll You Are My Rock ❤️ Love My Boys More Than Anything □ Best Feeling In The World! #BabyCarroll #LittleAC,” Billi wrote next to it.
SO CUTE.
