Taylor Swift makes peace with Katy Perry in You Need to Calm Down music video

It's hard to calm down after seeing the all-star celebrities in Taylor Swift's new music video.

The pop star shared her new You Need to Calm Down video on Monday.

The song, which debuted on Friday, is a cheeky anti-hate anthem that celebrates Pride.

For her upcoming new album, Lover, Swift has ditched the dark, sinister colour tones of her Reputation album in favour of candy-coated rainbow ones. 

The new music video follows suit, taking place in a wonderland of a trailer park, and ending with a buzzworthy scene of Katy Perry and Swift ending their long-running feud by embracing onscreen, with Perry as a hamburger and Swift an order of fries.

"A happy meal," Swift wrote on Instagram, with a photo of the pair hugging.

Elsewhere in the video, Swift lounges in a pool float, hosts a tea party, throws cake in a food fight and carouses with the video's many celebrity co-stars, such as Ellen DeGeneres and Laverne Cox.
