Can you guess who the most popular Irish guy on Twitter is?

Harry Styles better up his Twitter game because Niall Horan is catching up with him after hitting 19 million followers!

This makes him the most followed Irish man on Twitter –pretty impressive for a 20-year-old lad from Mullingar eh? He’s put Ronan Keating to shame too – he’s only got 478,000 followers.

Katy Perry is still the reigning queen of Twitter with 54 million followers, but we have no doubt that Niall will earn his crown in no time!
