Harry Styles seemed to have spent the night with Taylor Swift at her Greenwich Hotel in New York City. The One Direction member was spotted leaving the building Tuesday morning, December 4 before his rumored girlfriend made her exit separately.

Harry, 18, wore dark shades and a gray t-shirt. He also rocked the same black pants and brown shoes he donned the night when he went on an outing with his 22-year-old lady for an afterparty after One Direction's Madison Square Garden concert.

Taylor, meanwhile, traded her little black dress with a warmer and comfy outfit that consisted of a blue jacket and a pair of brown pants. "There were no fans," an eyewitness told E! News, "just paparazzi." She was reportedly on her way to Cookshop restaurant to meet friends for lunch.

The country/pop singer was not in attendance when her new beau performed with his band at MSG Monday night. She was dozen blocks away from the venue to attend an annual gala hosted by Robert F. Kennedy Center for Justice & Human Rights at Marriott Marquis Hotel.

She received 2012 Ripple of Hope Award for her humanitarian works and performed a "Red" song called "Starlight", which was inspired by the Kennedy matriarch, Ethel. She was all smiles as she posed with several members of the family without her ex Conor Kennedy in sight.

Harry, meanwhile, seemed to be in great spirits when rocking MSG with his bandmates. At one point during the gig, the British heartthrob reportedly played with a bra that a concertgoer had thrown to the stage. Although Taylor didn't watch the concert, she met him afterwards.

The blonde beauty went to the Hudson Hotel for a karaoke night with the band. She was spotted holding hands with him, wearing the same outfit she donned when leaving the Kennedy event. Their playlist included a Backstreet Boys song and a One Direction track which she took part to sing.

It's only been a few days since Taylor and Harry went public with their romance despite never confirming their relationship, but already she earned one hater. Hailie Scott Mathers, the daughter of Eminem, expressed her outrage toward the female singer for dating the British idol.

"if @taylorswift13 is really dating the love of my life @Harry_Styles i will not be happy.!" Hailie tweeted. "Dear @taylorswift13, please stop w***ing around with every guy you see. We all know you're only doing it so you can make another album."

She concluded, "I, am never, ever, everrrrr, listening to your music againnnn @taylorswift13. LIKE EVER."
