The break-up between Taylor Swift and Calvin Harris is getting pretty scandalous.

The latest rumor claims that the pop-country singer has moved on to actor Tom Hiddleston just weeks after she and Harris ended their relationship. And according to Wednesday's report from TMZ, Harris had his suspicions for a little while now.

Sources say that the music producer was skeptical of Swift for about a month even though they were in a "committed relationship."

"He's pissed and feels betrayed by her," the insider said.

The news of Swift and Hiddleston comes as a shock especially since there was a previous report that said the singer cared very deeply for Harris. According to Britain's Heat magazine, she felt like Harris was her perfect match.

"Taylor's completely torn apart over this," a source said via Irish Independent. "She believed Calvin was 'The One.' This was it as far as she was concerned. She can't believe it's over."

It was also mentioned that Harris was the one who ended it, leaving Swift in misery even though she seemed to know that he "wasn't happy."

"For Taylor, it came totally out of the blue when Calvin told her it was over and it wasn't working," the source said. "She's so heartbroken. She understands how difficult it is being with someone so high profile, but she thought he had a handle on it. But apparently not."

Ever since Harris's car accident in Beverly Hills, it appeared that things came into perspective and had to do what he felt was best.

"Calvin had been having doubts for months," an insider said. "His car accident two weeks ago really bought things to a head...it was after that he told Taylor it was over."

Swift has also apparently deleted all photos that include Harris from her Instagram account.
