Not so fast...
Although the inseparable twosome and seemingly new couple spent the last two nights together in NYC, the adorable duo has officially parted ways—for work commitments.
The handsome 18-year-old One Direction star tweeted a photo of himself at Madison Square Gardens in New York this afternoon, and just one hour later, the country star announced that she is in Nashville, Tenn., for the Grammy nominations concert.
"I'll be co-hosting the Grammy Nominations Concert live from Nashville tonight! 10/9c on CBS. Headed to rehearsals now. Psyched," she wrote on the social media site.
The young singers were practically joined at the hip while they were both in NYC. They were spotted singing karaoke and visiting the zoo. Plus, the pair spent not one, but two nights together at Swift's hotel.
The 22-year-old songbird's last high-profile relationship—with 18-year-old Conor Kennedy—reportedly ended because of distance, so she and Styles will undoubtedly have to jet-set back and forth if they are going to make this romance work.
