First there were rumors that Calvin Harris and Taylor Swift were dating, which we were into. He's hot and talented, she's hot and talented and let's be honest -- we'd love to see what they could come up with musically! But just two weeks ago the hunky Scottish DJ told the Capital FM Breakfast show Taylor is "the opposite of my type" and proclaimed that he'd swipe left (i.e., reject her) if he ever stumbled across her on Tinder!

In his defense, he could have been trying to keep their romance on the DL at the time, because after the news hit the internet last week, the duo were all over each other at Kenny Chesney's Nashville concert on Thursday.

But is it all for love or is this a possible business move too? While Calvin isn't exactly hurting in the cash department (he's worth an estimated $70 million), a source tells TMZ that "Calvin is the best businessman among DJs and knows the cache of dating the biggest pop star in the world." Calvin has apparently "developed feelings" for Taylor, but the source adds that Calvin is "wired for success and there's no hard dividing line separating his personal life from business."

Better watch your back, T. Swizzle!
