We already know that Taylor Swift and Harry Styles were practically inseperable while spending time together in New York City last week, but, of course, things got even more steamy between the new lovebirds when they didn't even know the cameras were watching.

While backstage at Z100's Jingle Ball concert on Friday, the duo was videotaped hanging out together by a fan -- and the camera even caught Taylor plant a kiss on Harry before excusing herself for a moment! Check it out!

Taylor and Harry continued to spend their Friday evening together at the Jingle Ball after party, where another fan photographed them performing the lift from Patrick Swayze and Jennifer Grey's iconic dance number in Dirty Dancing. Ummmm.. can you say adorable?!

Their romance continued over the weekend in England, where Taylor joined Harry and his 1D bandmates (who reportedly aren't too happy with the new relationship) for a string of performances and appearances. She even rode in their tour bus, Lindsay Lohan style!

How long do you think Haylor will last?
