The organization took to Twitter to share the emotional tribute, which featured sweet moments such as Grimmie speaking to fans, her appearance on The Voice, and performing at the iHeartRadio Music Festival.
“One year ago, she captivated our audience at the #iHeartFestival. Tonight, we remember the incredible life and music of Christina Grimmie,” the organization tweeted alongside the video.
Grimmie was shot and killed after performing at an Orlando, Florida, concert in June. The 22-year-old singer competed on season six of The Voice as a member of Adam Levine's team, finishing third.
While the iHeartRadio Music Festival made a special tribute to Grimmie, the singer was not included in the In Memoriam segment that aired at the Emmys.
"As is the case each year with the Emmys, the In-Memoriam segment is constrained by time and space," a spokesperson for the Emmys explained in a statement to ET.
"Every year, the telecast producer is unfortunately limited by the time available and cannot include every significant person who has passed in the telecast In Memoriam; therefore, we note everyone in the industry on our website In Memoriam and during a simultaneous In Memoriam crawl on our Backstage Live streaming program," the statement concluded.
