ORLANDO, Fla. — YouTube star and "The Voice" contestant Christina Grimmie was fatally shot by a man who later killed himself inside The Plaza LIVE in Florida Friday night, according to police.

Grimmie's publicist confirmed her death in a statement sent to WFTV. She was 22 years old.

"It is with a heavy heart that we can confirm that Christina has passed and went home to be with the Lord," the statement said, in part. "We ask at this time that you respect the privacy of her family and friends in their time of mourning."

The gunman died of a self-inflicted gunshot wound, according to Orlando police.
