I'm A Dad?(Niall Horan)

Prologue What would you do if your now famous (x-)boyfriend had to break up with you to try out on X-Factor? Niall broke up with Karlee Lingerton because he was going to try out on X-Factor and he didn't think a long distince relationship would work out. But Karlee didn't even bother to watch Niall on X-Factor once she found out she was pregnant with her and Niall's child as soon as Niall left. What happens when Niall comes back to Mullingar, Ireland to find out he has a one year old baby that he didn't even know about? Will Niall choose to be involved in Gabriela's (Gaby's) life or will he be to busy with his career to care?
