One Direction's Harry Styles and country crooner, Taylor Swift are definitely getting a lot serious these days. The new couple was recently spotted hanging out together at New York City. Now, rumor has it that the "Haylor" duo has gone to the extremes of "staying over the night." What went down at the Big Apple for this cute couple?

By the looks of it, all the British boys from the famous band, One Direction are already taken. Niall Horan was spotted holding hands with a blonde girl who is said to be his girlfriend while Liam Payne had reconciled with girlfriend, Danielle Peazer. Louis Tomlinson and Zayn Malik are still going on strong with their respective girlfriends. This leaves Harry Styles, the known playboy of the group.

However, Harry has apparently turned a new leaf and isn't the "playboy" any longer. The 18-year old singer was recently spotted hanging out with an old flame, Taylor Swift in New York City. "Directioners" immediately went on the defense and started tweeting hate and death threats at the Grammy Award winner, Swift.

Yet, all the hate doesn't seem to affect Swift nor has all the warnings from fans stopped Styles from continuing pursuing Swift. In fact, the cute park date wasn't the only thing that went down at the Big Apple. Sources had confirmed that the "Haylor" duo grabbed a bite to eat at Bond St. Sushi with Ed Sheeran, Harry's mom and his stepfather.

"They came in around 8 PM and shared a few rolls together. They sat at their own booth and were giggling a lot. Harry looked really happy. She was talking a lot and he was laughing at her stories. Their order included the tuna tarts, Chilean sea bass, tuna crispy rice, and sesame crusted shrimp rolls. Taylor drank Diet Coke and others enjoyed the sweet saketini," says the insider to Celebuzz.

After the sumptuous meal, the pair then headed to the One Direction after party. The party was said to have taken place at a karaoke joint where Harry and Taylor sang "Don't Go Breaking My Heart."

It appears as if things are definitely taking a turn for the scandalous because after the karaoke trip that lasted until 4 am, both Harry and Taylor were seen sneaking into Swift's New York hotel. In fact, it looks as if the "Haylor" did enjoy a great night.

Styles was spotted leaving the hotel with the same shirt he worn on the date prior and an iPhone charger. Afterwards, Styles took to Twitter confirming what could have went down at Swift's' New York suite.

"Last night was the best thing I have ever done," tweeted Styles.

Well, well, well, it looks like the "Haylor" duo is a real deal which might lead to even more death threats and broken hearts.
