While World War III seems possible any day now, 2018 might actually be more peaceful than predicted - at least in the pop world.

Taylor Swift and Katy Perry's four-year feud could finally be a thing of the past after both superstars were reportedly seen together on set of a music video.

Rumour has it that the 'Swish Swish' singer was spotted filming a cameo for Swift's 'End Game' music video, her new single featuring Ed Sheeran and Future.

Videos of Taylor filming dance scenes on a yacht in Miami made their way online last week and many believe that Miss Perry was on it with her, which matches up with E! News' latest reports.

E! have confirmed that the pair "made up while they were both in Miami and that [Katy] did film a cameo" so we guess hell has frozen over.

Taylor and Katy's fallout dates back to 2013 whenPerry hired dancers that had previously worked with Swift, and then the'Reputation'singer released a little song called 'Bad Blood' about it. Remember those days?

Earlier this summer Katy confirmed that she is happy to put the drama behind her, saying "I think it's time. There are bigger fish to fry, and there are real problems in the world. You know what I'm saying?"

We are ready for these two women to unite for better things so that people can stop pitting them against each other. Plus, we get a major music video moment from it? Even better!

Taylor, we are most'definitely''...Ready For It'.
