Taylor Swift is known to bring a special guest onstage at her sold-out concerts, and Tuesday night at the Staples Center in Los Angeles was no exception, when she brought out indie darlings Tegan and Sara!

Taylor paired up with the twins to sing their hit single Closer, and the results are unsurprisingly great.
Though this isn't the first time Tegan and Sara have surprised such massive crowds. The Canadian sisters are coming off festival performances at Lollapalooza and Osheaga in Montreal, where they joined Macklemore and Ryan Lewis on stage to perform the equal rights anthem Same Love.
