Out of all the One Direction guys, Niall Horan seems to be the most secretive when it comes to his love life. While he is almost always romantically linked to someone, the 1D member has never confirmed or denied any of the relationships, making it impossible to know who he ever really dated.
Most recently, the singer is being linked to Irish model Thalia Heffernan (what's with him hanging out with all these models?!) who he was spotted kissing at an after party. We guess it's time to add her to Niall's long list of rumored girlfriends.
