Eminem [1] was on fire at Sunday's iHeartRadio Music Awards! The rapper gave a chill-inducing performance of his new song [2], "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 [3] 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.
