Justin Bieber was understandably emotional as he paid tribute to the late Christina Grimmie earlier this week, as he dedicated a song to her during his show in Winnipeg, Canada.

The singer was lying on stage performingPurpose when he began to choke up, and was heard asking: 'Grimmie, can you hear me?'

Justin met Christina a few years back as she was close friends with his ex girlfriend Selena Gomez, whose stepfatherwas her manager.

The former Voice contestant was shot and killed as she signed autographs for fans after a gig on Friday (June 10), sparking an outpouring of grief from the entire world and her fellow musicians alike.

Her mentor when she was on the show, Adam Levine, has made the kind gesture of paying for her family's travel to the funeral, as well as any other costs they will be faced with.

Our thoughts are with her friends, fans and family at this difficult time.
