Calvin Harris has slammed rumors that he ended his relationship with girlfriend Taylor Swift after getting a happy ending massage. In fact, he's so pissed about the reports, he's threatened to sue!

“It’s not going to be a ‘happy ending’ for everyone I sue for defamation of character for all these bullsh*t stories bye bye,” he tweeted. Swift, then favorited the tweet.

According to a report on Radar titled, "Un-Happy Ending! Taylor Swift & Calvin Harris Break Up After Thai Massage Parlor Visit — His Big ‘Lie’ Exposed," Taylor "got some fresh material for her next album" and dumped her beau after a questionable incident at a massage parlor. LOL, what?!

Apparently things have gotten quite serious with the DJ and the singer, and Us Weekly reports that T. Swizzle no longer calls her man by his stage name. “Taylor always calls Calvin by his birth name, Adam, and never Calvin in private," a source close to the couple told the mag. “She’s head over heels. She hasn’t been in love like this before!”

So...when will the engagement rumors start then?
