Justin Bieber''s emotional tribute to Christina Grimmie

Ottawa: Pop star Justin Bieber paid an emotional tribute to the late 'The Voice' singer Christina Grimmie at a concert.

The 22-year-old heartthrob recently took out time during his concert in Winnipeg, Canada to remember Grimmie, who was shot and killed on June 10 in Orlando, US, reports aceshowbiz.com. 

In one video taken and shared online by a concert goer, Bieber is seen lying on the floor and heard singing, "Grimmie, can you hear me?" in between lyrics of his song "Purpose". 

He appears to be wiping tears off his face with his arm. 

Grimmie was fatally shot while she was signing autographs and selling merchandise after her show in Orlando late last week. The shooter named Kevin James Loibl killed himself after committing the crime. 

Grimmie was friend with Bieber`s former girlfriend Selena Gomez as the two toured together years ago. The late star was managed by Gomez`s stepfather Brian Teefey.
