The 22-year-old country popster and the 18-year-old boy-bander left a party at New York City's Crosby Hotel Thursday night hand in hand and subsequently rode back to Taylor's hotel together.
"Just got in the car and @z100NewYork is playing 'I Knew You Were Trouble'!! Yes!!!!" the 22-year-old country popster tweeted.
The lovebirds the press has already dubbed Haylor have been spotted out and about the Big Apple the past week, from singing karaoke to visiting the zoo. They took a brief break as Swift jetted down to Nashville, Tenn., for the Grammy nominations concert.
The "Sparks Fly singer" meanwhile opened up a little bit about her love life in the latest issue of Cosmopolitan UK, reportedly telling the magazine that while she's dated quite a bit and knows a thing or two about heartbreak (we're looking at you, John Mayer), she still hasn't figured out how to keep a man.
"[I don't know] how to make them last. I've never had a really long relationship, so I have no idea what that's like. Wish me luck for the future!"
We're pulling for you, Taylor!
