If you love Taylor Swift's "Bad Blood," then prepare to hear your new obsession: Alessia Cara's cover of "Bad Blood."

You may know Alessia from her awesome single "Here," and if you haven't heard it yet -- WHAT ARE YOU WAITING FOR (seriously). Alessia recently stopped by BBC Radio 1's Live Lounge where she covered T-Swift's big hit, and not only CRUSHED Taylor's parts but beautifully sang Kendrick Lamar's rap verses as well. The end result is seriously GORGEOUS.

T-Swizzle heard the incredible cover, and has given it her Swift Seal of Approval, and is totes a part of the Alessia Cara fan club. She tweeted along with a link to the video, "You're AMAZING, @alessiacara. Love this."
