Remember that insanely HIGHlarious video The Fox by Swedish band Ylvis we showed you?
Well, guess what? The band just got even bigger because they made their American debut on the Ellen show and CLEARLY, she's a big fan!
Such a big fan that she even performed the song LIVE with them! Yup, this song is officially an international sensation!
Too bad we couldn't see Ellen dressed as a furry though! Ha!
Check out their performance (above)!
