Harry Styles, Taylor Swift Hookup: One Direction Boy Bander Spends Second Night in Hotel With Conor Kennedy's Ex

Duo were out together singing karaoke until 4 a.m. the night before, then headed over to her downtown Manhattan hotel

Harry Styles went back for seconds!

The One Direction boy bander returned to Taylor Swift's New York City hotel Tuesday night carrying what appeared to be an overnight bag.

The 18-year-old Brit ran past photographers and into the Greenwich Hotel around 11 p.m. One cameraman called out to Harry to "have a nice night with Taylor!"

Earlier in the day, the "Live While We're Young" singer was spotted leaving Taylor's hotel. He and bandmates Zayn Malik, Liam Payne, Niall Horan and Louis Tomlinson had been out with the Red singer until the early hours of Tuesday morning.

Then shortly after 4 a.m., Harry and Taylor were spotted holding hands as they made their way into the country-pop star's hotel.

Looks like they really do know how to make sweet music together.
