The young couple, who recently vacationed in Utah, shared a kiss in Times Square at the stroke of midnight, and of course, Twitter was there to document the liplock.
In the pictures, "Haylor" are seen embracing and and sharing a romantic smooch.
Swift performed her hit singles "I Knew You Were Trouble" and "We Are Never Ever Getting Back Together" during New Year's Rocking Eve and wrapped her set just minutes before the countdown to 2013 began. How lucky for Styles!
"Can't. even. verbalize. how stoked I am for 2013!" Swift tweeted earlier in the night. Hm...we wonder why!
