Are Selena and Niall getting close?

They say actions speak louder than words, and if that saying holds true, we're not sure we believe Selena Gomez! You see, when asked if she was dating Niall Horan, she coyly replied, "Oh my God! No! I love him, I always have. He's amazing." But if that's the case, why is Selena throwing subtle hints that say that "Siall" is real? For example, she posted (then deleted!) a photo with the caption, "I have a serious thing for Mullingar guys," shouting out Niall's hometown. Not to mention, the pair have been spotted out together-even kissing-everywhere form L.A. to London. Interesting!
