Haylor ended 2012 and entered 2013 with a romantic kiss.

Taylor Swift, who performed on 'Dick Clark's New Year's Rockin' Eve' before the stroke of midnight, and boyfriend Harry Styles of One Direction shared a romantic kiss at midnight on New Year's Eve in New York City. These two kids – so in love!

Styles nearly missed his flight to NYC to celebrate the new year with his beloved, since he left his passport at home and had to retrieve it. Like really? Hazza, how the heck do you leave the house for an international flight without triple checking to make sure you have your proper documentation?

Disaster was averted, though, and he arrived in the U.S. in time to hit the Jay-Z and Coldplay gig in Brooklyn before heading back to Times Square watch his missus (no, seriously, that's what Olly Murs called T. Swizzle) perform while wearing sexy black leather pants. Millions may have watched Tay Tay's perf, but it was likely an audience of one for her!

The international couple also shared a warm and cozy hug, too. Sorry, Directioners, but the body language is incredibly telling. Haylor are the real deal.

Later that night, Haylor were spotted holding hands -- one of their favorite activities -- upon entering their hotel.

Hazza is living the life. He didn't have to work (aka perform with 1D). He just had to support his girlfriend and look good while doing it.
