Tori Kelly honored the late Christina Grimmie in a new YouTube video. 

The 23-year-old singer paid tribute to Grimmie by writing “Blink of an Eye," an emotional acoustic ballad. “This song was written for christina grimmie after she passed away tragically,” Kelly wrote in the video’s caption. “I needed to write this song.” As she mentions in her note, Kelly wrote “Blink of an Eye” along with songwriter Zac Poor. Kelly sings, “Can't help but think who you would be / If you just had the chance to turn 23.”

In light of recent violent events within the U.S., Kelly added: 

“even though this song had specific meaning, more recently i'm overwhelmed at the pain & the brokenness in the world today, & so this is really just me grieving. at all of it. life is so short.”

Many artists, musicians, and friends have paid tribute to Grimmie, among them Selena Gomez and Grimmie’s manager Brian Teefey, who set up a GoFundMe account to support her family.
