Taylor Swift is spending quite a bit of time with her new squeeze, Harry Styles from One Direction .

After spending Sunday at the Central Park Zoo, the two were spotted holding hands walking into Taylor's New York City hotel at 4 a.m. Tuesday following a late night of karaoke. According to E! Online , the members of One Direction sang a big hit from another boy band -- the Backstreet Boys '  "I Want It That Way" -- at the after party following their Monday night show at Madison Square Garden.  

Taylor joined up with Harry at the party following a gala where she received the Ripple of Hope Award from the Robert F. Kennedy Center for Justice & Human Rights.  That honor recognizes Taylor's charitable contributions in the past few years, including her 2011 Speak Now...Help Now tornado relief benefit concert.

Taylor brought her friend Dianna Agron of Glee with her to the event, where she performed her Ethel Kennedy -inspired song "Starlight."  Taylor's ex-boyfriend Conor Kennedy was not in attendance, avoiding a potentially awkward situation, but his father and a few other family members were there.
