Niall dished on the b'day planning in a new interview with radio station Spin 103.8, explaining that they'll be touring in the U.S. when he and Liam turn the big 2-1, so naturally they want to do it up big.
He explained, "I reckon myself and Liam are probably going to end up having a joint 21st because his birthday is about two weeks before mine. We'll have a few drinks there. We've been touring America for the last three years and not been able to touch a drop."
Coming up soon for Nialler? Playing a Where We Are tour date on home turf at Dublin's Croke Park, which he explained, "Croker is going to be unbelievable, we're all saying it...It's been awhile since we've been in Dublin last, I haven't been home since Christmas."
