Take note, folks: One Direction's Harry Styles and Taylor Swift will now be known as #Haylor. The two pop superstars were spotted in the Big Apple over the weekend and quickly prompted a new batch of romance rumors as they became the subject of the Twitter trend and hashtag, Haylor.

They were photographed walking through Central Park together on Sunday. They stopped by the zoo, and according to some reports they were spotted chilling with Harry's stylist Lou Teasdale, her fiancé Tom and their baby, Lux. Additionally, some photographers caught the casually dressed pair walking through the park arm-in-arm and smiling by themselves. They also were photographed sharing some snacks on their stroll.

The photos of the rumored couple quickly prompted many an emotional response from fans, who took to Twitter to express their feelings on Haylor. "Y'all going crazy about Haylor when it hasn't even been confirmed," @mljyx wrote. "Maybe they are just dating like getting to know one another?!"

"What Do U Think About Haylor?" @MonicaTeodora17 wrote. "I Think they Will Be Great Together <3 ~Pixie."

Other fans noted their speculation about the twosome, "‏@sun_loves1D I think Haylor is only a friendship! and I hope it is..."

While fans like @kea_sarmiento remained even-keeled in their response (she wrote: "Haylor... Being a swiftie and a directioner.. I don't know what to say.. As long as they're happy, I don't really mind"), other fans seemed more outraged by the public date between the pair. @themalikfeels wrote, "If haylor gets confirmed I'm moving to the wanted's fandom I heard there's still space for few more."

One Direction take fans "deeper" in their 3-D movie!

Taylor and Harry first sparked romance rumors this spring after they met at the Kids' Choice Awards in March and the boys later hinted at something during an MTV News interview in April. After what seemed to be a cooling off period, Taylor and Harry then met up again during an "X Factor" taping last month in L.A.

It seems that there might be more opportunities for Haylor photo ops this week as both acts are slated to play Madison Square Garden on Friday for Z-100's Jingle Ball. 1D will play the legendary NYC venue days prior, on Monday night.

Will One Direction, The Wanted End Their Feud In NYC?

In other 1D relationship news, Liam Payne sparked his own set of headlines when he was spotted in New York walking hand-in-hand with his ex, Danielle Peazer. The couple ended their two-year relationship back in September, but looked to be very much back on strolling around NYC together. Zayn Malik's GF, Little Mix singer Perrie Edwards, and Louis Tomlinson's girl, Eleanor Calder, are also rumored to be in town for the boys' MSG gig.

And, how do the fans feel about that reunion? @OnexDirectionnn wrote, "Seeing Peazer back together makes me really happy! but then you have Haylor..." @LouissCarrots1D added, "I would much rather talk about Payzer than haylor. IM SOOOO EXCITED THAT THEY ARE BACK ON <3 <3."

The rumored couple also took in the zoo's various sights — including a seal, which left Swift giggling and Styles with a perplexed look on his face.
