Grimmie, who was shot fatally at her final concert in Orlando, Florida on Saturday, participated in the sixth season ofThe Voice. Levine was her celebrity coach.
Levine signed Grimmie to his music label,222 records, following the competition two years ago and has remained close to her since.
"Behati and I are absolutely devastated and heartbroken by Christina Grimmie's death. Our hearts go out to her family," tweeted Levine.
"[Adam Levine] personally called my mother and said he will pay for the funeral and her plane flight," claimed an overwhelmed Marcus Grimmie, the brother of Christina, who tackled her attacker after the shooting.
A rep for Levine confirmed that the former Maroon Five singer would be paying for the funeral.
Manager for Grimmie, Brian Teefey, began a GoFundMe page to fund the expenses of her family.
"[The money is] to help our family move out of our current house and to take care of the funeral," posted Marcus on Facebook.
"Please do not feel the need to donate anything at all," continued Marcus. "Please, just leave a kind word, message or picture in the comments or message me and sign this change.orgpetition to help Christina possible be remembered in the next legend of Zelda game, her favorite game of all time."
As of Monday, the GoFundMe had accrued almost $172 thousand in donations.
"Words cannot express...literally I have no words," remarked Marcus.
