They say imitation is the sincerest form of flattery.  But what happens when someone takes a song that you wrote, recorded and had a huge hit with . . . and just takes you to school on it?  That's exactly what has happened to Taylor Swift, courtesy of fellow pop diva Jessie J, who just tore into Taylor's smash "I Knew You Were Trouble" during a recent live performance on BBC Radio 1's Live Lounge.  This is a ridiculous master class in singing and Jessie completely reinvents Taylor's hit song.  This chick rocks!

Love it!  Love it!  Love it!  And I just snagged some tickets to see Jessie J next March when she opens for Robin Thicke at the Fabulous Fox Theatre in St. Louis.  Jessie, if you're out there.  If you happen to be reading this on  PLEASE!!  Sing this song live in concert.  That is all.  Thank you!
