Performing a medley of hits during Dick Clark's New Year's Rockin' Eve With Ryan Seacrest, Swift, 23, stuck around after her concert with hundreds of thousands of revelers in New York City's Times Square to watch the clock strike midnight. By her side as the singer ushered in 2013: None other than new boyfriend Styles, 18.
As throngs of onlookers and police officers stood by, Swift and Styles shared a smooch for all the world to see. In the fan video above, the couple can be seen embracing as the iconic songs "Auld Lang Syne" and "New York, New York" are played.
"Can't. even. verbalize. how stoked I am for 2013!" Swift tweeted earlier in the night Dec. 31.
Dating for one month, Swift and her boy band beau have sure made the most of their time together. Over the Christmas holiday, the pair joined Justin Bieber and Selena Gomez for a double date ski trip at Canyons Resort in Park City, Utah. Prior to their getaway, Swift tagged along with Styles in his hometown of Holmes Chapel, England, where she bonded with his big sister, Gemma, 22, at the Rising Sun pub in Bamford and gushed about how "amazing" he was.
"I can see them getting married in a week, just going for it," an insider tells Us Weekly of the hot-and-heavy twosome.
