After expressing his grief in a heartfelt statement, her Voice coach Adam Levine reached out to Grimmie's family to help out with funeral costs, her brother revealed on Facebook.
"I found out this morning, that Adam Levine personally called my mother and said he will pay for the funeral and her plane flight, and I was blown away," Grimmie's brother, Marcus, shared in a post about the touching news.
In the same post, Marcus thanked fans for their support over the last few days, including generous donations on a GoFundMe account set up by Grimmie's longtime manager Brian Teefey.
"Now a friend just told me to look at the gofundme page and I see it is at 100k. Words cannot express...literally I have no words," he wrote. "Please do not feel the need to donate anything at all. Please. Just leave a kind word, message or picture in the comments."
He also urged fans to sign a change.org petition so Grimmie can "be remembered in the next legend of Zelda game, her favorite game of all time."
In a statement to WHO, Levine offered his condolences to the 22-year-old singer's family and remembered her as a brilliant talent.
"[My wife] Behati and I are absolutely devastated and heartbroken by Christina Grimmie's tragic death," says Levine in the statement. "Our hearts go out to her family. Christina was a natural, a gifted talent that comes along so rarely. She was taken from us too soon."
"This is yet another senseless act of extreme violence. I am left stunned and confused how these things can conceivably continue to happen in our world," he continued.
