Eminem was on fire at Sunday's iHeartRadio Music Awards! The rapper gave a chill-inducing performance of his new song, "Nowhere Fast," featuring Kehlani. At the start of it, Eminem added an intro about gun violence in the wake of the Marjory Stoneman Douglas school shooting in Parkland, FL. "Gun owners clutching their loaded weapons," he rapped. "They love their guns more than our children." Watch Eminem's impassioned performance above.
