Justin Bieber could scarcely keep his emotions in check on Saturday night while paying tribute to Christina Grimmie.
In footage that is now making its way across the Internet, Bieber actually collapses to the ground while singing the lyrics to "Purpose" at the MTS Centre in Winnipeg, Canada.
“Grimmie, can you hear me?” the artist said while fighting back tears during the emotional performance, which was captured by fans on their cellphones.
By now, we all know the tragic story behind Christina Grimmie.
She was shot and killed on June 10 while signing autographs for fans after a show in Orlando.
According to various reports, a deranged fan approached Grimmie with a gun and simply started firing.
Her brother tackled him to the ground and likely spared the lives of many others in the area, prior to this mad man turning the gun on himself and committing suicide.
Grimmie was a contestant on The Voice and Bieber met her through Selena Gomez, whose stepfather served as Grimmie"s manager.
Selena also paid sad tribute to Grimmie on stage over the weekend:
Adam Levine, meanwhile, has since offered to pay for Grimmie"s funeral, while fellow The Voice judges Christina Aguilera, Gwen Stefani, Pharrell Williams and Blake Shelton offered their condolences on Twitter.
A candlelight vigil was held for Grimmie in her native New Jersey town on Monday evening, with her brother speaking out at the event.
