The long list of Taylor Swift duets continues to grow. This time the singer teamed up with British sensation Charli XCX during a Toronto performance for her 1989 Tour. Not only were the audience members surprised when the two joined forces to perform "Boom Clap," Charli XCX also debuted two pieces from her upcoming collaboration with the U.K. high-street retailer

The English star looked oh-so-cool on stage as she rocked matching separates that were anything but boring. She hit the stage in an animal print crop top, which featured a cut-out neckline and yellow furry trimming at the end of the long sleeves. Likewise, her pants were just as much fun with the same print, a high waist silhouette, and a bell bottom finish.

Charli XCX is known for her standout punk rock voice, and it looks like her collaboration with Boohoo will be just as extraordinary. But fans will have to wait a few more days to score the trend setting pieces. All 18 pieces will officially launch worldwide on October 26 on
