Watch Miranda Sings and Tori Kellys Cover of Bad Blood
Taylor Swift's "Bad Blood" got a makeover from YouTube star Miranda Sings and musician Tori Kelly  and Swift herself called the duo's cover "the vocal event of the year" on Twitter. In the video, Sings a character portrayed by comedian Colleen Evans keeps up her persona as a terrible singer who thinks she's, well, not a terrible singer. Meanwhile, Kelly plays the guitar and tries to keep a straight face. After Swift tweeted out the link to the video, Sings replied by thanking her  and offering her services. "If u want I can give u voice lessons,"she wrote on Twitter. "I'm a gr8 teacher." See just how great of a vocal coach she is in the video above.
