The newly brace-less boybander is rumoured to be romancing Irish model Zoe Whelan.
It seems our prediction that he would be kissing more ladies after having his teeth straighteners removed turned out to be right.
According to The Sun, the couple have been secretly dating for a few months after meeting backstage at a 1D gig and things have developed pretty quickly.
She attended Niall's brother's wedding last month, which insiders say is a sign he is serious about her.
However, Zoe has quickly learnt about the perils of dating a One Directioner, and has been forced to delete her Twitter account after receiving abuse.
One tweeted: “So @Z_Whelan is the girlfriend of niall hope that girl make my babe happy , cuz if she broke the heart of niall i KILL THAT BITCH.”
Another wrote: “@Z_Whelan i don’t know who you are, but i will find you and i will kill you. not kidding.”
While Niall has been busy romancing his new girlfriend, his bandmates have been getting into a massive fight with The Wanted on Twitter.
