American singer and The Voice US contestant was targeted by a gunman who opened fire on her and then killed himself, her publicist has confirmed.
The horrific incident occurred at a concert venue in Florida, just as Christina signed autographs after a show. She was rushed to hospital in a critical condition but later died from her injuries.
Her publicist, Heather Walsh, said in an email early on Saturday that “we can confirm that Christina has passed and went home to be with the Lord”.
The Orlando police department also confirmed on its official Twitter page that Grimmie had died.
The investigation is ongoing into why the gunman attacked the singer but police called the shooting a "very tragic event" and praised Grimmie's brother as "a hero". Her brother tackled the shooter after he opened fire.
Christina, who was born in New Jersey, finished third during season six of The Voice US, competing on the team of Maroon 5 star Adam Levine.
The Voice paid tribute to Grimmie on its official Twitter page.
