Settle down, everyone. Lady Gaga is a self-professed heavy metal fan and has even been spotted at the legendary Kuma's Corner in Chicago. Don't get your underwear all twisted yet and take a look at this video, which exploded in 2011 and has nearly eclipsed 3 million views. 

Mashups are always pretty entertaining and this might be the best one yet! Lady Gaga's hit 'Judas' is intertwined with the Judas Priest barnburner 'Painkiller,' yielding a blend of hilarity and puzzled looks of surprised enjoyment. It's quite scary how well these two songs work together and we challenge you to disagree!
