Taylor Swift might be having a tough time with her break-up from Calvin Harris.

The two called it quits a couple weeks ago, and according to Britain's Heat magazine, the country-pop icon is pretty heartbroken. Apparently, she felt like she may have found her perfect match.

"Taylor's completely torn apart over this," a source said via Saturday's report from 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 mentioned that Swift didn't see the split coming although she supposedly "knew Calvin 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."

Just recently, Harris got into a car accident in Beverly Hills, California. He had to cancel four shows to recover from the crash. Surprisingly enough, the accident may have contributed to the break-up.

"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."

According to a report from E! News, one of the main reasons why it didn't work out for Swift and Harris-- whose real name is Adam Wiles-- is because they were just too different.

"Taylor wanted more attention than Adam gave," a source said. "Adam did care very deeply for her but the breakup was bound to happen."

Earlier this month, Harris took to Twitter to say that he and Swift have a "huge amount of love" for each other following their split.
