Taylor Swift and Charli XCX Perform 'Boom Clap' in Toronto: Watch
Charli XCX is a big fan of Swift’s music. Earlier this year, she gave the pop star’s “Shake It Off” a punk rock twist during an appearance on the BBC's Live Lounge. Check out the wild cover in the video below.
On Friday night, during her first of two sold-out shows at Toronto’s Rogers Centre, Swift returned to her country roots with the help of American Idol judge Keith Urban. The country star strapped on a guitar and joined Swift for a performance of his new single “John Cougar, John Deere and John 3:16" and "Somebody Like You."
