In an interview with Access Hollywood, Stefani revealed that the entire Voice community, including all of the judges, were shocked and troubled by the former contestant's death.
"Everybody, you know, is shaken," Stefani shared in an interview. "It's just a shock and... it makes me feel totally vulnerable."
Grimmie appeared on Season 6 of The Voice and continued her rise to stardom on YouTube.
She was only 22 when a man opened fire following her concert in Orlando. Police have confirmed that Grimmie and the man did not know each other personally before the incident, leaving fans wondering why he picked Grimmie in the first place.
Stefani was not a part of the show when Grimmie took home third place back in 2014, but she still felt the impact of the singer's tragic end.
"Everybody is just horrified," Stefani added.
It is still unknown why the man killed Grimmie before fatally shooting himself. Fortunately, no one else was hurt during the shooting.
Although there is no personal connection between the gunman and Grimmie, Music Times is reporting that she was specifically targeted by the man.
John Mina, the police chief in Orlando, revealed that the man, one Kevin James Loibl, was also well armed during the shooting and may have wanted to kill more people. Along with two loaded handguns, Loibl was carrying extra clips and a hunting knife.
There were security guards at the event, though none of them were armed. They did, however, check fans as they entered The Plaza. They searched bags and purses for signs of contraband but did not have a metal detector on hand.
Christina Grimmie was quickly rushed to the hospital after the shooting, though she eventually passed at Orlando Regional Medical Center that same night.
Fortunately, Grimmie's brother was quick to react and subdued gunman moments after he opened fire on Grimmie, who was signing autographs at the time. Before police arrived on the scene, however, Grimmie's shooter died from self-inflicted gunshot wounds. He was only 27-years-old.
"It is with a heavy heart that we can confirm that Christina has passed and went home to be with the Lord," Heather Weiss, a spokesperson for Grimmie, stated. "We ask at this time that you respect her family and friends in their time of mourning."
"This should have been something that was fun and exciting and of course when something like this happens it's just a tragedy," she shared.
As fans will recall, Grimmie worked with Adam Levine during her time on The Voice and came close to winning it all.
Following her time on The Voice, Grimmie managed to gather a lot of support through YouTube, where she would frequently share her opinion on popular songs.
At this time, it is unclear what motivation Loibl had in killing Grimmie. Hopefully, more information will be released in the coming weeks that will clarify the unfortunate incident.
In the meantime, it isn't known if ABC is planning of memorializing Christina Grimmie with a special on The Voice. Considering how her death affected all of the judges on the show, it wouldn't be surprising if producers put together a special tribute next season.
