The couples romance is heating up! Taylor Swift and Harry Styles got out of New York's Crosby Hotel on thursday eve to celebrate a friend's bday (other stars at the party were Emma Stones and Dianna Agron). A source attending the party told PEOPLE: "Taylor and Harry were being very smoochie,” “They definitely looked like a couple.” And according to the source they held hands and Harry seemed "really protective of her" as he held his arm around her during the celebration. They kissed and didn't seem to mind if anyone saw them. The source continues with saying: “They’re not trying to hide it. The bar was packed.” This is not the first time though, that they're seen together! Last sunday they were seen visiting the Central Park Zoo and on monday, Swift attended a Madison Square Garden show afterparty at the Hudson Hotel for Styles’ band, One Direction, where the couple joined for a karaoke duet of a Backstreet Boys song. And before they headed back to the hotel together, Swift sang a One Direction tune. Aww, how cute! We really, really wish they're meant for eachother! Can we agree on that they'd be such a hot couple?!
