Taylor Swift and Harry Styles Hold Hands During a Late-Night Rendezvous

It's on between Taylor Swift and Harry Styles.

In the wee hours of Tuesday morning, the apparent new couple was seen holding hands as they arrived at the One Direction star's Manhattan hotel. It marks their first PDA moment since they started quietly spending time together last month.

Earlier in the evening, Swift attended the Robert F. Kennedy Center's Ripple of Hope Holiday Gala at the Marriott Marquis, where she was honored by her ex-boyfriend Conor Kennedy's famous family for her commitment to social change through music. Although the evening had the potential to be awkward (hanging with the ex's family!), the 22-year-old country singer looked beautiful on the red carpet in an Oscar de la Renta gown with gold embellishments, and she later took to the stage to perform tracks from her latest album, Red.

After the gala, Swift made a quick wardrobe change into a LBD before leaving to meet Styles. He and his 1D bandmates headlined a sold-out concert at Madison Square Garden — during which one fan tossed her bra at the 18-year-old on stage! — then went to an afterparty at the Hudson Hotel, where Swift joined him. After hanging out until nearly 4:00 a.m., Swift and Styles returned to his hotel. As they exited their car in front of the hotel, Styles grabbed Swift's hand and guided her into the lobby.

All signs have pointed to a relationship between Swift and Styles. Last month they were spotted holding hands on "The X Factor" set, a tidbit the show's host Mario Lopez shared on his radio show. This past Sunday, "Haylor" visited Central Park with friends. They obviously weren't trying to hide during the park outing — the popular NYC tourist spot draws an average of 175,000 visitors a day.

Expect more PDA to follow as Swift and Styles will be in New York City all week. They have a couple days off before they both are set to perform at Z100's Jingle Ball, again at Madison Square Garden, on Friday. However, knowing Swift and her relationship track record, they may also be splitsville by then. If that happens, we're sure she'll at least get a good song out of it.
