Taylor Swift might be adding onto her relationship rap sheet with a new rumored beau, Ed Sheeran.

The two musical collaborators have released a duet, "Everything has Changed," bringing some on-stage chemistry that seems to imply more than just making sweet music together, according to Perez Hilton. After just recently singing the intimate tune on "Britain's Got Talent," it looked like a relationship was developing in front of the audiences' eyes.

But despite some "googly eyes," the two are reportedly just friends. But a few reports hint that they are an item.

The blonde singer and her crooning partner shared a quick peck on the cheek after their surprise performance at Capital FM Summertime Ball in London, according to UK's Glamour.

And both are currently entertaining audiences around the country on the RED tour, having had some killer late night jam sessions.

At the recent Billboard Awards, Swift even reportedly pranked Sheeran, according to SugarScape. 

"Taylor got me a seat next to her," the red-haired guitar maestro told Radio 1. "But I didn't know what to do as at a British ceremony, like the BRIT Awards, you just sit there and get drunk. But Taylor told me that at an American awards when someone wins, you stand up and clap, and when someone performs you stand up and dance."

He continued, "Then she left me on my own in the front row as she had to perform. Nicki Minaj and Chris Brown were behind me, so then after the first award I stood up and no one else did. It was embarassing...it was awkward." 

There had been rumors that the two reported best buddies were having relations, but Sheeran shut those down in having said he would never go there with her, also reported SugarScape.

"You don't have to bang a girl just because she's your friend," he said to The Sun. "It's not a necessity. So that's why I'd never go there with her. I wouldn't want to spoil things."

And since he is also close with Swift's ex-boyfriend, Harry Styles, many people suspect he is telling the truth. 

But the two still look to close for comfort in public so we will let you be the judge. Tell us what you think below!
