Calvin Harris cheated on Aarika Wolf with Taylor Swift?

DJ Calvin Harris reportedly started getting close to now rumoured girlfriend Taylor Swift while he dated model Aarika Wolf.
The 31-year-old Scottish DJ "pretended that the Taylor Swift stuff happened after" he ended his relationship with the model, reported Aceshowbiz.
Sources said Harris confessed to a friend that he was cheating on Aarika with the singer before splitting. Swift, 25, apparently did not know about his relationship with the model when they first hooked up.
"Calvin and Aarika met on the set of his music video 'Blame' in August, and they started officially dating in October. They were full-on boyfriend/girlfriend for about six months," an insider said.

Harris reportedly "waited a while for the dust to settle before stepping out" with Swift in late March.
They were first spotted together at a Whole Foods in March 25 and later acted cozy at a Kenny Chesney concert two days later.
"He ended up breaking up with Aarika, and then just pretended that the Taylor Swift stuff happened after (the breakup). Aarika probably knows now that she was cheated on," the insider said.
