Christina Grimmie's heartbroken family pay tribute to their daughter at her funeral.

Family and friends of late Voice star Christina Grimmie have paid their respects to the singer in a touching memorial service, where she was remembered as someone who had a definite “impact” on the world around her.

Grimmie’s heartbroken brother and parents addressed the crowds in Medford, New Jersey, after their daughter and sister was shot dead by a deranged fan just over a week ago.

Her brother Marcus told those attending that he will miss his sister’s generous self, where her “arms were open” for “everyone”.

“I don’t have anything to say, I don’t have words still and it’s a good and bad thing. All I’m going to say is thank God for the mark that she left on this world. Thanks mom and dad I know it’s going to be really tough for us to move forward,” he said.

"All the rumours are true that when the gunman came, her arms were open. That's how she treated everyone she knew, her arms were open for them. So thanks again for coming out you guys, and I love you Christina."

Since the devastating attack, Marcus has been hailed a 'hero' after he jumped in front of gunman Kevin James Loibl, tackled him to the ground and ensured there were no other casualties that fateful night.

Grimmie's mother also publicly paid tribute to her daughter, similarly acknowledging the heroism of her son and the important of his loyalty and support since the passing of Christina.

"Marcus, I want to say this publicly and from everyone," she began. "I want everyone to know he has been so good to his moma. He has loved me and he has stood by my side."

It was Grimmie's father, however, who detailed the harrowing affect his daughter's death would have on his future, outlining how his life will never be the same without her.

"There's this gigantic hole in my heart that I know is never going to go away," he told the masses, according to E! News.

Despite this, he promised the crowds that his daughter was in a better place.

Grimmie rose to fame after appearing on The Voice in 2014, blowing the judges away with her cover of Wrecking Ball in the Blind Auditions. Watch the audition here. Post continues after video...

"She's way better off now, she's more alive now than she's ever been, she's not going to be hurt anymore."

The memorial service came after singer and former Voice mentor Adam Levine offered to pay for the funeral service, after Grimmie's manager created a GoFundMe page to raise money for the performer's funeral.
