Singer Alessia Cara covered T-Swizz's hit on BBC Radio 1, and pulled it off with only a piano, guitar and random finger snaps. For the performance, she stripped down the kickass anthem, and didn't forget about Kendrick Lamar's part, either. She totally takes that on, and kills it.
Taylor tweeted about the girl's rendition, and of course, Alessia freaked the eff out.
