So, Taylor Swift basically shut down the Internet with the release of her single Shake It Off last night, but today has brought a brand spankin' new must-watch video courtesy of HAIM. The LA mega-babes (and former ASOS Magazine cover girls <3) teamed up with crazy-cool Harlem rapper A$AP Ferg for a remix to their track My Song 5, and the results? Beyond. The ladies of HAIM enlisted famous pals like Vanessa Bayer (you'll recognize her from her dead-on Miley Cyrus impersonations on Saturday Night Live), Vampire Weekend hunk Ezra Koenig, Twilight's Xavier Samuel, Grimes and Ke$ha. Yep, Ke$ha. Not convinced yet? They all appear on a Maury-style show. Cue the audience shouting: "HAIM! HAIM! HAIM!"
