It is no secret for anyone, Gym Class Heroes are famous in part because of Fall Out Boy's Pete Wentz, who has been a sort of role model/ mentor for so many bands on the scene. So, Wentz and his partner in crime Bebe Rexha, who work together under the moniker of Black Cards, have recently posted a remix of their friends in GCH's Ass Back Home, which has garnered attention, peeking at #3 on the iTunes pop hits.
