Apparently, Taylor Swift and Harry Styles didn't just do a duet or two. Rumor has it that the "Haylor" duo got involved in a dirty act that left onlookers pretty speechless. Does this have something to do with the fake photograph of Harry Styles kissing Taylor Swift at the said karaoke after-party?

Twitter users have been re-tweeting what looks to be a photo of One Direction's Harry Styles lifting Taylor Swift. It obviously looks like Styles has been practicing his dirty-dancing moves. The said photo was taken at the after-party of the boys' show at Madison Square Garden in New York last Friday.

"Harry Styles gives Taylor Swift a "lift" at the One Direction MSG After Party!!" tweeted the onlooker.

Some have been saying the photo is another fake but comparing it to what Harry and Taylor were wearing that night at the karaoke party, the dirty-dancing photo is truly the "Haylor" duo.

If anything, this couple is becoming the fastest developing romance in Hollywood history. According to a source to Heat Magazine, Taylor and Harry were actually an item month's back even before Conor Kennedy came into the picture.

"Harry and Taylor first started dating back in March of this year, before she fell for Conor Kennedy. Source told Look: 'They had a couple of dates back when they met, but the timing wasn't right. They were busy with work, then Taylor met Conor Kennedy and fell hard for him. But she and Harry stayed in touch throughout the summer," explained the source.

This best explains why Swift managed the "swift" move-on from Kennedy to Styles in just a few days.

"As soon as Harry found out Taylor was single again, he went after her. Dating has always been a bit of a cat and mouse game for him, and he's never really had a girl say no to him before," added the source.

While some "Directioners" are still questioning the sincerity of the "Haylor" couple, some sources claim that Harry and Taylor are nothing but enamored with each other.

"They are being more open about their relationship as they have taken it to the 'next level'. Harry has been introduced to a handful of Taylor's closest friends and even her mum, and Taylor has been hanging out at the boys' hotel a lot. It seems like she's spent every single night with Harry since he arrived," says the source.

If this photo of Harry Styles and Taylor Swift caught dirty-dancing can cause so much talk, what more could a photo of them kissing manage to do?
