Watch Selena Gomez sparked rumors of a new romance when she was recently spotted out in London with One Direction heartthrob Niall Horan. The pair appeared to be having a great time together on their night out and they even stopped to pose for fun pictures with fans. And this isn't the first time the two pop-stars have been linked! Niall previously admitted that he had a crush on Selena, but he didn't want to get involved due to his friendship with her on-again and off-again boyfriend, Justin Bieber. But now that Selena and Justin appear to be officially over, maybe the Irish singer was finally ready to come and get it..
