It's unreal that it was 9 months ago when we told you that One Direction's Niall Horan is going to be a uncle but now the baby has been born and Niall could not be happier!
The singer posted for a photo with his new little nephew and posted the photo on Twitter with the caption:
"Congrats Greg and Denise! Wohoooo! I've got a nephew! Cutest kid ever!"
We know that Niall's fans have been going crazy for this photo and we wonder how the little baby will feel knowing how famous his uncle is.
