Niall Horan off the market??

Please tell me it isn't so!! Is One Direction's Niall Horan off the market? Last night, a friendly tweet by the one and only, Niall Horan, sent various Directioners, or Niall girls, to their maximum level of insane. Niall's tweet telling people to follow Ella Scally, who just so happens to be his ex-girlfriend, Holly Scally's, younger sister, caused a few heart breaks in some girls with their thoughts that the two might be rekindling the fire.

Now we all know that Holly and Niall split up back in 2010 before he auditioned for The X-Factor, the show that completely changed his life, but could it be that maybe they have some unfinished business? While the 1D cutie has not confirmed if anything is going on, there are still various Directioners waiting for an answer, until then Niall and the rest of the boys from One Direction gather up their gear and prepare for their North American tour.
