A sweet person who will always do anything to make you smile! He is the sweetest boyfriend, if you're lucky enough to win his heart and will be 10000% faithful.

Don't mess with a Niall, because if you do, then you'll have everyone who he knows after you!!

He is the sweetest person who doesn't ever seem to be full. This bundle full of Irish is too sexy to not love!!
Person 1: OMG did you hear Niall is dating Nicole?
Person 2: Yeah, she is so lucky! She better treat him right otherwise I'll hunt her down!!
