The argument started back in 2011 when Calvin Harris, scheduled to open for Katy's gig, cancelled last minute due to set arrangements. But with the release of the video-which both briefly prolongs the lifespan of "Swish Swish" and signals that the end is near-it's still worth ruminating on the whole saga, a freaky and memorable faceplant by a one-time Teflon pop artist whose career had up to this point been a smooth ascent to the top with an extended ride at cruising altitude.

The ending sees The Tigers winning, and they throw a party to celebrate.
Earlier this month, while appearing on SiriusXM's The Morning Mash Up, Perry revealed that she and Swift have yet to speak about their possible reconciliation.
